Description
Engine load servo device and its dynamic optimization operation control method technical field
The present invention relates to engine control, relate more specifically to a kind of fuel engine load servo device and its dynamic optimizing control method.Background technology
Experiment shows, fuel engines exports some mechanical output and there may be the operating point that several different rotating speeds and moment of torsion coordinate, there is an oil consumption minimum point, as the best match operating point of rotating speed-moment of torsion in multiple operating points of some mechanical output of engine output identical.It is exactly the optimum efficiency operation curve of the engine by the curve that the oil consumption minimum point under different output power is connected and made smoothing processing acquisition.The fuel engines efficiency highest on the curve, the mechanical energy that the fuel oil of consumption equivalent is obtained is maximum.
As can be seen here, when fuel engines is operated under certain rotating speed, if applied to the moment of torsion on its axle and the moment of torsion of the optimum efficiency operation curve requirement under current rotating speed are same, engine is to be operated on the best efficiency point of current rotating speed.Engine is under different rotating speeds, moment of torsion of the moment of torsion remained applied on axle always with optimum efficiency operation curve requirement is same, that is rotating speed-moment of torsion of engine matches with the requirement of optimum efficiency operation curve, the fuel oil of engine consumption equivalent will can obtain the mechanical energy of maximum, reach most economical running status.
Various fuel engines are each equipped with grade speed changer and buncher in current vehicle
Etc. (CVT) mechanical transmission mechanism, to adjust the rotating speed and moment of torsion of matching, expects that rotating speed-moment of torsion matching of fuel engines approaches optimum efficiency operation curve.
Most commonly used step change transmission has 4-5 speed stage, can carry out easy speed regulation, but gear ratio can not be continuously adjusted.When changing situations such as load torque is because of windage, load-carrying, road conditions, environment, abrasion, the moment of torsion put under the different rotating speeds of different shelves on engine shaft seldom can be consistent with the requirement of optimum efficiency operation curve.
A kind of buncher it is main by active wheels, driven wheels, metal tape and hydraulic pressure pump group into, and the consecutive variations of gear ratio are realized with the radius of clean-up that V-type transmission belt is engaged by changing driving wheel, the driven pulley conical surface, so as to realize that engine speed-moment of torsion is preferably matched.But there is also obvious limitation for buncher：It is that mechanical structure is more complicated thus its manufacturing cost is high first；Furthermore the inertia of mechanical structure and hydraulic system is big thus governing speed is slow, when engine throttle or external loading moment of torsion dynamic change, particularly road conditions frequently change, throttle frequently changes,
When busy shift, buncher（CVT gear ratio) can not be rapidly and accurately adjusted, the probability that fuel engines is operated in optimum efficiency operation curve is still very low；Other buncher
(CVT) transmission efficiency is less than general gear-shift mechanism.These shortcomings all have influence on CVT popularization and application.
Fuel engines configures moment of torsion servo-loading unit, can be according to the optimum efficiency operation curve prestored in the actual speed and main control unit computer of engine, the torque data matched by current rotating speed, corresponding moment of torsion is applied to fuel engines by the motor of servomechanism installation, can be so that fuel engines be operated on the optimum efficiency operation curve prestored, the operational efficiency of fuel engines is substantially increased, energy-conservation is obvious.
But because the fuel engines characteristic of same model there is also dispersiveness, it can not possibly unify, in addition with external factor such as the continuous aging of fuel engines parts, the change of fuel oil used, the change of air ratio, the changes of engine temperature, the actual optimum efficiency operation curve of fuel engines often deviates the optimum efficiency operation curve obtained by initial producer provides or experiment.That is when the optimum efficiency operation curve initially stored by servo-loading unit controls fuel engines, obtained moment of torsion is calculated with stored optimum efficiency operation curve according to current rotating speed, is not the moment of torsion for obtaining optimum efficiency matched with the rotating speed.That is servo-loading unit does not make on the real optimum efficiency operation curve that fuel engines is operated in after change, thus energy-saving effect will discount.The content of the invention
Because of the change of the factors such as engine parts situation or fuel qualities, the data that the rotating speed of fuel engines optimum efficiency is matched with moment of torsion can change.This fuel engine load servo device and its optimizing of progress control method energy automatic dynamic, real-time amendment engine optimum efficiency operation curve, make engine remain operating on actual optimum efficiency operation curve, reach the purpose for further saving the energy.

The first rotor 4 of the present apparatus or the winding being wound on iron core, collector ring 6 are arranged on engine shaft 2, and the winding is connected by collector ring 6 with servo-driver 8.Second rotor 5 is then the rotor of embedding permanent-magnet material, is that the first rotor 4 provides magnetic field, other structures are same as described above.
Fuel engines installs the above-mentioned servo-loading unit matched with its peak torque with maximum speed.Installation rate/position sensor 3 on motor first rotor 4, speed/positional sensor 3 is connected with the computer and servo-driver 8 of main control unit 9.On the oil circuit of fuel engines 1
Flow sensor 11 is also equipped with, flow sensor 11 is connected with the computer of main control unit 9.Position sensor 10 is installed, position sensor 10 is connected with servo-driver 8 on the axle of motor second rotor 5.
The exemplary process block diagram of this fuel engine load servo device dynamic optimization operation control method referring to Fig. 3 to this method as shown in figure 3, illustrate.
When fuel engines 1 is run, speed/positional the sensor 3 current rotating speed of monitoring the first rotor 4 and position, and by rate signal N (revolutions per minutes in real time）Main control unit 9 is delivered in real time, position signalling is delivered into servo-driver 8.Position sensor 10 monitors the current location of the second rotor 5 in real time, and position signalling is delivered into servo-driver 8.
Main control unit 9 is based on present speed signal N, and matching best torque T (N.m, Newton meter is determined according to the optimum efficiency curve prestored）, and servo-driver 8 is sent into torque value T setting.Torque setting that servo-driver 8 is sent according to main control unit and the second rotor 5 tried to achieve according to the position signalling of the second rotor 5, the first rotor 4, the relative position signal of the first rotor 4 load the current phasor of the winding of the second rotor 5, engine output shaft is set to bear torque T, while the output shaft of the second rotor 5 externally exports an equal amount of moment of torsion.
On the basis of torque value T derived above, main control unit 9 performs automatic optimal program, increases torque value to start optimizing, and assign optimizing to be designated just with the long dT of optimizing step pitch automatically.Main control unit 9 sends into servo-driver 8 with T+dT setting, torque setting and the second rotor 5, the relative position signal of the first rotor 4 that servo-driver 8 is sent according to main control unit load the current phasor of the winding of the second rotor 5, and control fuel engines 1 is with torque T+dT trial operations.
Main control unit is obtained under speed N, torque T+dT states in optimizing measuring and calculating time dt (h, hour from the flow sensor on oil circuit）Interior fuel consumption, and according to present speed 1, torque T+dT calculate fuel engines exported within the dt times mechanical energy W=N x (T+dT) x dt/9550 (kWh, kilowatt-hour）, it is derived from fuel engines specific mechanical energy fuel consumption value, i.e., fuel consumption M/W (g/kWh, gram/kilowatt-hour of every kilowatt-hour mechanical work between this trial run period）.
Compare rotating speed in the case of N, the rotating speed that the specific mechanical energy fuel consumption data of fuel engines 1 and the computer of main control unit 9 of optimizing test run torque (T+dT) are stored is the oil consumption data of corresponding points on optimum efficiency operation curve in the case of N.If being less than the oil consumption index on optimum efficiency operation curve in the specific mechanical energy fuel consumption that trial operation point in time dt is calculated in optimizing, i.e. optimizing success then replaces original T to be stored in the computer of main control unit 9, optimizing with T+dT
It is designated just constant, the computer of main control unit 9 continues (to notice that now T has been updated over as stated above with T+dT）Optimizing again., whereas if moment of torsion is in T+dT trial operation, specific mechanical energy fuel consumption is more than the data on optimum efficiency operation curve, i.e. optimizing and failed, then change optimizing and be designated negative, and reverse optimizing.The computer of main control unit 9 sends into servo-driver 8 with torque T-dT, controls the output shaft of fuel engines 1 trial operation under this moment of torsion, and compare its fuel consumption.If being less than the oil consumption index on optimum efficiency operation curve in the specific mechanical energy fuel consumption that T-dT trial operations point in time dt is calculated in optimizing, that is optimizing success, then original T is replaced to be stored in the computer of main control unit 9 with T- dT, optimizing is designated negative constant, and the computer of main control unit 9 continues (to notice that now T has been updated over as stated above with T- dT）Optimizing again., whereas if moment of torsion is more than the data on optimum efficiency operation curve for T- dT trial operation specific mechanical energy fuel consumption, then changes optimizing and be designated just, and positive optimizing again.
In the case that rotating speed N is constant, with T+dT and T- dT iterative cycles, Stepwise optimization and update, and when rotating speed changes, optimizing circulation restarts.The rotating speed moment of torsion matched data continuous renewal that so can keep optimum efficiency curve is actual optimum data, fuel engines 1 is always worked on actual optimum efficiency curve, reaches optimum energy-saving effect.
Computer can thousand pre- automatic optimal program as needed, stop or restart.After automatic optimal program stopped, main control unit 9 is according to present speed signal N, and the optimum efficiency curve according to storage determines matching best torque T, and torque value Τ setting is sent into servo-driver 8, control engine operation.Restart automatic optimal program then still by the process flow operation of above-mentioned steps.
The long dT of optimizing step pitch selection follows two principles：One is that optimizing is quick enough, and this requires that dT is larger；Two be that optimizing point is close enough, in order to avoid dT crosses optimum point, this requires that dT is sufficiently small.DT preferably can be in the range of 0.1 ~ daNm, but not limited to this.It is different with the speed of engine optimal economic operation curve rate of change according to the arithmetic speed speed of the computer of main control unit 9, determine dT size.The arithmetic speed of the computer of main control unit 9 is very fast, then dT is smaller；Engine optimal economic operation curve rate of change is very fast, then dT is larger.DT is less than the 5% of nominal torque, in order to avoid cause control to be vibrated.
Optimizing calculates time dt preferably in the range of 0.1-5 second, but not limited to this, specifically relevant with the fuel consumption measurement speed and precision of flow sensor 11.For example fuel consumption measurement speed, precision are higher, then dt is smaller.
In one embodiment, 1.8L discharge capacities petrol engine installs this servo-loading unit, and using the operation of this transition operation control method.A points as shown in Figure 2, are worked in engine
Power output 15kW operating mode and in the case of keeping constant, if engine is operated in the revolutions per minute of non-economy operating point 3500,40.9 Newton meters, then the oil consumption of its unit output mechanical energy amount is 335 grams/kilowatt-hour.But engine working point is adjusted to the B points on optimal economic operation curve by this add load control and this progress control method, that is 1302 revolutions per minutes, 1 10 Newton meters, then the oil consumption of its unit output mechanical energy amount is reduced to 250 grams/kilowatt-hour, reduces oil consumption 25.4%.When the change because of fuel oil quality or engine scuffing, when the optimum efficiency operation curve is actual, and 10% skew occurs in the point, if still pressing the moment of torsion control of virgin curve, oil consumption 1 % ~ 20% higher than minimum.The present apparatus and method dynamically update optimum efficiency curve, and oil consumption is minimum when exporting same mechanical energy.Depending on operating point, different, drift condition is different, then fuel-economizing situation is also different, but can keep maximum energy-saving state.
