Background
For flight simulation equipment, trimming is a common method and technical means in the development process of flight simulation equipment software. Based on the rapid balancing method of the existing flight simulation equipment, parameters such as flight parameters, control surface angles and engine thrust which meet balancing conditions can be calculated. For a pneumatic trim result obtained through theoretical calculation, each system is required to respond so that the whole flight simulation equipment can reach a theoretical calculation state, and the pneumatic trim result comprises a flight system model, a flight control system model, a power system model and the like. The flight system responds to flight parameters such as airplane attitude, airflow angle and the like calculated by balancing; responding to the control plane deflection angle calculated by the trim of the flight control system model; the powertrain model (engine simulation model) responds to the trim calculated thrust. For a power system, the trim thrust obtained by theoretical calculation needs to be controlled by the power system to control an accelerator lever, and the thrust output by a model is calculated by a power system simulation model to be consistent with the trim calculation result, so that the power system model meets the state of complete machine trim. The above-described process of the powertrain is hereinafter referred to as powertrain balancing, i.e., balancing of the engine simulation model.
The traditional power system balancing method is that under the condition that the input of other systems is not changed, the difference value between the current thrust and the target thrust of the power system is judged, and whether the preset tolerance is met or not is judged. If the tolerance is met, exiting the iterative loop, and considering that the balancing of the power system is finished; if the tolerance is not met, multiplying the difference value of the current thrust and the target thrust by a gain coefficient to serve as the movement amount of the throttle lever, calculating to obtain a new current throttle lever position, calculating to obtain a new thrust state by taking the current throttle position as the throttle lever input of the power system, comparing the new thrust state with the target thrust, and iterating until the tolerance is met.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
It should be noted that, in the description of the embodiments of the present invention, the terms "comprises," "comprising," or any other variation thereof are intended to cover a non-exclusive inclusion, so that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but also other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrases "comprising a," "8230," "8230," or "comprising" does not exclude the presence of additional like elements in a process, method, article, or apparatus that comprises the element. The terms "upper", "lower", and the like, indicate orientations or positional relationships that are based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and to simplify the description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. Unless expressly stated or limited otherwise, the terms "mounted," "connected," and "coupled" are to be construed broadly and encompass, for example, both fixed and removable coupling as well as integral coupling; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The terms "first," "second," and the like in this application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. Further, "and/or" indicates at least one of the connected objects, the character "/", generally indicating that the former and latter related objects are in an "or" relationship.
The main characteristics of the engine simulation model can be divided into static characteristics and dynamic characteristics, wherein the static characteristics refer to that the thrust of the engine tends to be stable after a period of time corresponding to the fixed throttle lever position in a specific flight state; the dynamic characteristic means that a certain time is required to elapse from the starting of the throttle lever to the moment when the thrust reaches a stable state, and the time is related to the current flight state, the position of the throttle lever and the movement rate of the throttle lever.
Then, due to the dynamic characteristics of the engine simulation model, the trimming of the conventional engine simulation model has the following two problems:
firstly, the thrust resolved by the current throttle lever position cannot represent the engine thrust in a stable state, so that the tolerance judgment of the difference value between the current thrust and the target thrust has a deviation, and the final power system balancing result is not ideal.
Secondly, if the gain of the throttle lever movement is reduced, the deviation caused by the dynamic characteristics can be slightly reduced, but the problems caused by the deviation are that the power system trimming time is very long, and the dynamic deviation cannot be completely eliminated; in addition, if the gain setting is too large, it may cause a jump in the vicinity of the target point to fail to reach the target state.
The invention improves and solves the problems on the basis of the traditional balancing method of the engine simulation model, and the main idea is as follows:
after the difference value between the current thrust and the target thrust of the power system (an engine simulation model) is calculated, the processing of the movement amount of the throttle lever is modified into the movement rate, and the processing is carried out in a segmented processing mode. The specific method comprises the following steps: the method comprises the steps that N sections of thrust difference value intervals of current thrust and target thrust are preset, each section of thrust difference value interval corresponds to different throttle rod moving rates, and the overall principle is that the smaller the numerical value of the thrust difference value interval is, the slower the moving rate is. Namely, the thrust difference value of the current thrust and the target thrust is calculated, the thrust difference value interval to which the current thrust and the target thrust belong is judged, and the moving speed of the throttle lever is further determined.
In order to solve the steady state deviation generated by the dynamic characteristic of the engine simulation model, a silent time window method is adopted for processing. The method comprises the following specific steps: when the difference between the current thrust and the target thrust meets a preset tolerance, the balancing of the engine simulation model is not immediately determined to be completed, and a certain preset time (silent time) is waited for, so that the engine model is continuously solved under the current throttle lever position. After the silent time, the deviation of the current thrust and the target thrust is recalculated, and the movement rate of the throttle lever is determined. And iterating in the above way until the current thrust is still kept within the preset tolerance range after the silent time, and confirming that the engine balancing is finished.
Based on the above main ideas, a balancing method, a balancing device, an electronic device, and a storage medium of an engine simulation model according to embodiments of the present invention are described below with reference to fig. 1 to 5.

Wherein the quiet time may be set to 5 seconds.
Step 105: and taking the actual thrust as a new current thrust, and returning to the step 101 until the final completion of the balancing of the engine simulation model is determined after the temporary balancing of the engine simulation model is determined to be completed at least twice continuously.

Wherein, the preset tolerance can be set to 50 newtons (N), and the specific value can be set according to the trimming requirement.
Fig. 2 is a schematic flowchart of a method for calculating a current thrust provided by the present invention, and as shown in fig. 2, in step 103, updating the current thrust according to a thrust difference interval in which the thrust difference is located includes:
step 201: and determining the preset movement rate of the throttle lever according to the thrust numerical value interval in which the thrust difference value is positioned.
And the thrust numerical value interval corresponds to the movement rate of the throttle lever one by one.
Optionally, in a case that the thrust difference is less than or equal to the preset tolerance, determining that the throttle lever moving speed is 0.
For example, the preset throttle rod movement rate is determined according to the thrust value interval where the thrust difference value is located, and the specific formula is as follows:
wherein the content of the first and second substances,Rto be the rate of movement of the throttle lever,Dis the thrust difference;D1，D2，D3，D4 is a preset thrust difference value;R1，R2，R3，R4，R5, presetting the moving speed of the throttle lever; wherein the content of the first and second substances,D1>D2>D3>D4，R1>R2>R3>R4>R5=0，D4 is a preset tolerance.

Step 203: and determining the updated current thrust of the engine simulation model according to the current throttle lever position.
It should be noted that, in the present invention, the thrust of the engine is calculated according to the current throttle lever position of the engine simulation model, which belongs to the technical means that those skilled in the art can understand, and is not described herein again.
Optionally, in step 104, after a preset silence period elapses, calculating an actual thrust of the engine simulation model, including:
continuously resolving the thrust of the engine simulation model according to the current throttle lever position of the engine simulation model within a preset silent time;
and after the thrust of the preset silent time is resolved, taking the finally resolved thrust as the actual thrust.
Alternatively, in step 105, the actual thrust calculated in step 104 is used as a new current thrust, and the process returns to step 101 to iterate. Determining that the trimming of the engine simulation model is finally completed after determining that the temporary trimming of the engine simulation model is completed at least twice in succession.

Hypothetical hairThe target tolerance of the motor trim is 50N, and 4 preset thrust difference values are set in total, wherein the two preset thrust difference values are respectively as follows:D1、D2、D3、D4; dividing the thrust into 5 intervals by 4 preset thrust difference values to respectively correspond to the intervalsR1、R2、R3、R4 andR5, 5 preset throttle lever moving rates.
Wherein the content of the first and second substances,D4=50 is the target tolerance,R5=0, which means that when the current thrust is smaller than the target tolerance 50N, the throttle lever movement rate is 0, i.e., the current position is maintained. In addition to this, the present invention is,D1>D2>D3>D4，R1>R2>R3>R4>R5。
after the engine simulation model is subjected to balancing, the method is executed according to the following steps as shown in FIG. 3:
step 1: timing and accumulating the quiet time, carrying out no treatment on engine balancing in the quiet period, and carrying out normal calculation on the thrust of the engine by the system at the current throttle lever position;
step 2: calculating a thrust difference D between the current thrust and the target thrust after the quiet period;
and step 3: judging the relation between the thrust deviation of the current engine thrust and the target thrust of the engine and a preset tolerance, and entering the step 4 to the step 7 if the thrust deviation is greater than or equal to the preset tolerance; if the deviation is smaller than the preset tolerance, entering the step 8 to the step 9;
and 4, step 4: timing the trimming completion time to zero;
and 5: and setting the movement rate of the throttle lever according to the belonged range of the thrust deviation, and calculating the movement rate R of the throttle lever according to the following formula:
and 6: calculating the position of the throttle lever according to the movement rate of the throttle lever;
and 7: normally calculating the current thrust of the engine according to the position of the throttle lever, and returning to the step 1;
and 8: resetting the silent time to zero, setting the moving speed of the throttle lever to 0, considering that the engine simulation model completes the temporary balancing, and performing the balancing completion timing accumulation of the engine simulation model;
and step 9: and (4) judging whether the engine balancing finishing time is greater than T1, finishing balancing if the engine balancing finishing time is greater than T1, and returning to the step 1 to enter a quiet period if the engine balancing finishing time is not greater than T1.
Therefore, the method can complete the calculation of the engine balancing through the steps and ensure that the thrust deviation of the final balancing result and the target thrust is within the preset tolerance range. Specifically, the method solves the problem of influence on the balancing result caused by the deviation of the thrust corresponding to the current throttle lever position and the thrust in a stable state due to the dynamic characteristic of the engine by using a silent time window method; furthermore, the problem that the fluctuation in the target field cannot reach the leveling value due to the fact that the throttle lever moves too fast under the condition that dynamic deviation is uncertain or the problem that the leveling time is too long due to the fact that the throttle lever moves too slowly is solved through a mode of processing the moving speed of the throttle lever in a segmented mode.
