The Ziegler-Nichols PID Parameters Setting Method Based on the Ideal Relay Feedback Identification and its Improvements

Article Preview

Abstract:

This paper analysized the Ziegler-Nichols setting method based on the ideal relay feedback identification. There are errors in the method. So, we consider to adopt hysteresis relay feedback to countact the error generated by the load disturbances and improve the measurement accuracy to eliminate errors. We proposed a PID parameter setting method stability margin method based on the hysteresis relay feedback identification. It can be seen from a plenty of simulation experiments that the control performances of the methods in set value tracking and interference eliminating are very good.
