Design of Fuzzy-PID Controller and Its Simulation

It is difficult for general PID to control systems with nonlinear and large delay properties.Therefore,a Fuzzy - PID controller is proposed by combining the advantages of both the simple Fuzzy Control and traditional PID control.This control algorithm can be divided into two steps;building the fuzzy rules by simulation and analysis,obtaining the parameters of PID controller by reasoning;realizing real - time control by fuzzy - PID.And by computer simulation and comparison,it is concluded that the use of the method in the system can greatly improve the robustness and the dynamicstatic properties of the system.
