Study of M-FPID Control for System with Large Time-Delay and Parameter Uncertainty

摘要

There are many systems with large time-delay and parameter uncertainty in industry processes. Using common PID controller cannot get good control results. This paper presents a set of fuzzy PID control modes in order to overcome large time-delay by analyzing the feature space of dynamic response. The relevant control mode is dispatched according to different dynamic response characters. Furthermore, the study and analysis of several simulation examples show effectiveness of M-FPID control.
