CONTROLLING A MOTOR OF A CLOSURE AND/OR BLIND IN A VEHICLE BODY BASED ON A DISTURBANCE OBSERVER SIGNAL

A controller for controlling a motor of a closure and/or blind in a vehicle body is configured to determine a reference state signal (82) comprising speed and/or current measurements, repeatedly estimate motor model parameters of the motor, determine an estimated state signal (84) based on an input...

Summary:A controller for controlling a motor of a closure and/or blind in a vehicle body is configured to determine a reference state signal (82) comprising speed and/or current measurements, repeatedly estimate motor model parameters of the motor, determine an estimated state signal (84) based on an input signal (81) comprising measurements or estimates of a voltage, the estimated motor model parameters, the reference state signal and an error signal (122), the error signal representing a difference between the reference state signal and the estimated state signal, determine a disturbance observer signal (112) from the error signal, compute a first derivative of the disturbance observer signal at a present moment, and reverse the motor upon determining that the first derivative of the disturbance observer signal exceeds a threshold.
