Abstract
A system for the closed-loop control of a positioning unit in a motor vehicle with the system's loop controller supplying a signal to the positioning unit dependent upon a comparison between a predetermined-value signal and an actual-position signal. The predetermined-value signal depends upon the desired position of the positioning unit and upon the output signal from a signal-forming device. Based upon the predetermined-value signal and by simulating the control loop, a simulator generates an estimation signal for the actual-position signal. This estimation signal influences the response characteristic of the signal-forming device.
Claims20
A system for the closed-loop control of a positioning unit in a motor vehicle, comprising:
- a loop controller coupled to the positioning unit, the loop controller providing a first signal to the positioning unit, the first signal depending upon an injection signal and a comparison between a second signal and a third signal, the second signal depending upon the desired position of the positioning unit, the third signal representing the actual position of the positioning unit;
- a signal-forming device coupled to the loop controller, the signal-forming device forming the injection signal dependent upon a pseudo system deviation, the pseudo system deviation being the difference between the second signal and the fourth signal;
- and
- a simulator coupled to the signal-forming device, the simulator receiving the second signal and providing a fourth signal, the fourth signal being an estimation of the actual position of the positioning unit.
A system for the closed-loop control of a positioning unit in a motor vehicle, comprising:
- a loop controller coupled to the positioning unit, the loop controller providing first signal to the positioning unit, the first signal depending upon a fifth signal and a comparison between a second signal and a third signal, the second signal depending upon a desired position of the position unit, the third signal representing the actual position of the positioning unit;
- a signal-forming device coupled to the loop controller, with the signal-forming device generating the firth signal;
- and
- a simulator coupled to the signal-forming device, the simulator receiving and processing the second signal to provide a fourth signal, the fourth signal being an estimation of the actual position of the positioning unit that control generation of the fifth signal by the signal-forming device.
