Fuzzy Control And Its Application To Model Reference Adaptive Predictive Control

Since fuzzy mathematics was firstly presented in 1965,in the latter decades,fuzzy control was widely used in many fields successfully.Based on the analysis of the actual curves for power plant controlled processes(such as steam temperature control process) and interference of controlled systems,a parallel Fuzzy/PID MRAPC method is provided, which is one of linkage for MRAPC and Fuzzy control methods.For this case,this paper introduces a new control strategy,which is the compound of fuzzy control and model reference adaptive predictive control,using fuzzy self-adjusting PID instead of self-tuning PID;Based on the analysis of the output signals trend by measurement, applied in the suppression of greatly disturbance in abnormal discontinuous working condition.This paper introduces the principle,the composing,control flow and the simulation of this control strategy in details.And the base control rule is according to the results of the optimization with genetic algorithms.The implement of the control strategy in MRAPC achieves good results and proves its correctness and feasibility.
