Research on Modeling and Simulation of Expert_PID Controlled Servo System Based on MATLAB/S-Function

The paper elaborates Expert_PID controller applied in servo system. Illustrates an S-function construction method on complex control law. Designs an Expert_PID controller based on MATLAB/S-function and writes partial core code of Expert_PID controller. Establishes the simulink model of servo system based on Expert_PID control law, gets the simulation result. Compared with the traditional discrete PID control law, the result demonstrates that Expert_PID controller can obtain excellent control qulity.
