Abstract

Plenty of previous motor speed control system approaches are based on the assumption that motor speed to be controlled is available for measurement. In order to get more accuracy, the assumption is not suitable, while the time lag problem the processing time of the control program and the motor speed detecting may cause the system unstable. This paper proposed to use a predictive state observer to reconstruct actual motor speed, calculate the estimated value of the instaneous speed of the next sampling instant before the actual next sampling instant is reached. Comparing their results it has shown that this new approach is better then the conventional ones.
