The Research on the Parameter Tuning Method of an Analytic Type Fuzzy Integral Hybrid Controller

Abstract

This paper proposed the method of Analytic Type Fuzzy Integral Hybrid Control (ATFIHC)regarding the difficulties of realization of fuzzy control algorithm and the steady state error of the fuzzy control system. The parameter tuning equations of ATFIHC are obtained on the basis of the corresponding relations of parameters between the analytic fuzzy integral controller and the classic PID controller, then the grid search method was applied to obtain the coefficients of the parameter tuning equations. The result of simulation shows that the control effect of the ATFIHC is superior to the optimized PID controller in integral norms such as IAE, ISE, ITAE and control norms such as Overshoot and Response Time, and it is more adaptive to the changes of parameters and structure of the controlled objects.
