Definitions
- Thread transfer drive in particular for a workstation of a textile machine
- the invention relates to a yarn laying drive, in particular for a workstation of a textile machine, according to the preamble of patent claim 1.
- the non-prepublished document DE 103 54 587 A1 describes a special angle transmitter for the already described thread guide or wiper.
- the u. a. consists of an analog Hall sensor and a magnet, the actual angular position of the thread guide is detected and passed to an unspecified control or regulation of the thread guide drive for further processing.
- the actual angular position of the thread guide can be determined quickly and precisely by the disclosed angle encoder, this does not solve the previously mentioned problem of the previously used controllers or controls.
- the controller comprises a multi-variable control in order to precisely regulate the angular position ( ⁇ _ist) of the yarn guide by means of the at least one manipulated variable (u) for the real controlled system.
- ⁇ _ist angular position
- u manipulated variable
- the output stage and the electromechanical laying drive of the thread guide form the real or actual controlled system.
- the object of the invention is advantageously set up for generating at least one non-measured input variable in addition to the at least one measured input variable of the controller.
- ⁇ _soll predetermined angular position
- M_soll the corresponding moment
- ⁇ _rios_soll the corresponding angular acceleration
- ⁇ _soll the corresponding angular velocity
- I_soll necessary current
- the controller also has information about the moment (M_soll), the angular acceleration ( ⁇ _ gleich_soll), the angular velocity ( ⁇ _soll) and the necessary drive current (I_soll) before. Due to the precalculated laying curve, the control or the controller can thus prevent an overshoot of the yarn guide at the reversal points of the coils as well as other laying errors at high yarn laying speeds. Of course, this only applies as long as no disturbances occur.
- the setpoint values of the moment (M_soll), the angular acceleration ( ⁇ _yak_soll), the angular velocity ( ⁇ _soll) and the laying flow (I_soll) do not have to be stored in addition to the desired size of the angular position ( ⁇ _soll) for each laying curve of a winding structure, are determined via a system model, which simulates the real controlled system in terms of control engineering or mathematics, from the respective angular position ( ⁇ _soll) calculates the missing variables for the ideal controlled system.
- the setpoint of the angular positions ( ⁇ _soll) on the one hand goes directly into the controller and on the other hand into the model of the ideal controlled system in parallel.
- the torque (M_setpoint) corresponding to the respective angular position ( ⁇ _setpoint), the corresponding angular acceleration ( ⁇ _point_setpoint), the corresponding angular velocity ( ⁇ _setpoint) and the necessary routing current (I_setpoint) are determined on the basis of the ideal controlled system and are passed as output variables of the system model into the controller as another Setpoint variables for the multi-variable control.
- the controller also the comparable actual values, which consist of the actual angular position ( ⁇ _ist) of the thread guide, the current moment (M_ist), the current angular acceleration ( ⁇ _yak_ist), the current angular velocity ( ⁇ _ist) of the yarn guide and the existing laying current (I_ist) , to the incoming setpoints available. Since in practice a number of disturbances on the actual controlled system act, needed the control additionally the actual values of these variables in order to be able to compensate for a deviation of the actual values from the desired values. These actual values can, for example, be detected directly by additional sensors or measuring probes or calculated indirectly from other physically detectable measured variables and forwarded to the controller by means of a feedback.
- a further measure improving the invention provides that the comparable actual values (to the setpoint values of the controller) can be determined by a state observer according to the real controlled system as so-called estimated values ( ⁇ _dach, M_dach, ⁇ _ gleich_dach, ⁇ _dach, I_dach) and sent to the controller ( be forwarded by the already mentioned feedback), wherein the state observer at least one manipulated variable (u) of the controller and the actual angular position ( ⁇ _ist) are present as input variables.
- the state observer itself is another time-invariant model, whereby the desired actual values can be reconstructed.
- the values obtained by the observer of the state are called “estimated values", they are by no means “estimated values” but rather specific or calculated values.
- the connected observer makes it possible to communicate the internal states as they exist in the real controlled system sufficient accuracy to determine and provide the controller.
- ⁇ _act the angular position
- the additional measuring sensors can also be prevented by the condition observer employed. This can be used on the existing technical structure or the structure of the thread-laying drive.
- the status observer is designed as a Luenberger observer or as a so-called asymptotic observer.
- Luenberger observer reference is made, for example, to Otto Föllinger "Control Engineering", Dr. Alfred Wilsonhig Verlag Heidelberg 1990. On pages 502 et seq.
- the proposed Luenberger observer has the advantage that with its help the system state can be reconstructed exactly after an initial disturbance, in particular for disturbances which repeat themselves from time to time Since the observer is able to recapture the new system state, the use of the Luenberger observer makes it possible to precisely control the thread transfer drive, even in the event of disruptions.
- a weighting of the individual desired and actual values by weighting blocks is provided separately in each case in the controller, whereby the control quality of the controller can be further improved in a simple manner.
- the respective weighting of the individual values can be determined experimentally, for example.
- the individual nominal and actual values can be weighted not only linearly but also potentially or exponentially by the weighting modules.
- the control quality can be further increased in a simple manner by this measure.
- control differences of the individual setpoint / actual values can be detected by the controller, for example, after a weighting has been carried out, and the controller can carry out a correction of at least one manipulated variable (u) for a control difference not equal to zero.
- the controller can carry out a correction of at least one manipulated variable (u) for a control difference not equal to zero.
- an angle sensor for detecting the actual angular position ( ⁇ _ist) of the thread guide which has an analog Hall sensor and a magnet, in particular a permanent magnet, which are in operative connection with each other. Further details and application examples can be found in DE 103 54 587 A1. Of course, however, an optical (digital) angle sensor for detecting the actual angular position ( ⁇ _ist) of the thread guide can also be used instead of the analogue Hall sensor.
- a computer which simulates at least the system model and / or the state observer control technology or mathematically, makes it possible to implement the present invention inexpensively and easily. If such a computer is used, it can also be used for the controller. This allows the simplify technical design of the invention further, and save additional costs.
- the invention enables high thread laying frequencies while avoiding installation errors.
- the existing technical structures of the thread-laying drive are utilized.
- the angular position ( ⁇ _soll) is advantageous as a setpoint on the one hand directly into the controller and on the other hand as an input to an upstream system model, which simulates the real control system control technology or mathematically.
- this upstream system model further setpoint values, such as the angular velocity ( ⁇ _soll) corresponding to the angular position, the corresponding moment (M_soll), the corresponding angular acceleration ( ⁇ _ gleich_soll) and the necessary laying current (I_soll) are determined for a multi-variable control of the controller.
- the angular position ( ⁇ _dach) can be determined from the manipulated variable (u) of the controller and the actual angular position ( ⁇ _ist) of the thread guide via a state observer.
- the thread guide, the corresponding angular velocity ( ⁇ _dach) of the thread guide, the corresponding moment (M_dach), the corresponding angular acceleration ( ⁇ _yak_dach) and the current required for laying power (I_dach) of the drive are generated as estimated values and the controller as further input variables (by a feedback) available stand. In this way, the regulation also reacts to any disturbances that are thus compensated.
- Figure 1 is a block diagram of the exemplary control structure of the thread laying drive.
- FIG. 1 shows a block diagram for the control structure of the thread laying drive with a status observer 12.
- the predetermined angular position ( ⁇ _soll) as setpoint value 2 directly enters the controller 4.
- this angular position ( ⁇ _soll) as Input variable used for the system model 3.
- the real controlled system 10 which consists of the final stage of the yarn guide drive and the further electromechanical yarn laying drive, shown as an ideal controlled system.
- the additional setpoints 2 namely the corresponding moment (M_soll), the required laying current (I_soll), the corresponding angular velocity ( ⁇ _soll) and the corresponding angular acceleration ( ⁇ _ddling_soll) of the yarn guide, can be generated as additional input variables for the controller 4.
- a weighting of the incoming nominal quantities 2 can be provided separately for each nominal variable 2 individually by weighting modules 5.
- the controller 4 can also respond to possible disturbance variables 14 which act on the real controlled system 10, actual values which are present at the end of the real controlled system 10 are also used as the basis for a comparison with the desired values 2.
- the actual values are fed back to the controller 4.
- the desired actual values are supplied as estimated values 13 from a state observer 12 to the controller 4, since the existing actual values can only be determined with a disproportionate effort.
- the state observer 12 makes it possible to determine the comparable estimated values 13 to the required actual values on the basis of the manipulated variable 9 (u), which represents a voltage, and the controlled variable 11, which consists of the actual angular position 11 ( ⁇ _ist) of the thread guide.
- control variables 9 (u) output by the controller 4 are forwarded to the real controlled system 10, whereby the angular position of the yarn guide is changed.
- the actual angular position 11 ( ⁇ _ist) of the yarn guide is detected by an angle sensor or sensor, not shown, and represents the actual controlled variable 11 of the illustrated control system. This controlled variable 11 is the only, actually determined actual value of the entire control system.
