Simulink simulation software based on MATLAB is implemented. The simulation and application results show that the expert PID control has better control effect than the conventional PID, and has the advantages of simple and easy to get. This paper mainly studies the design and application of the expert PID controller: (1) the principle of PID control and PID control is introduced in this paper. (2) the controlled object transfer function G (s) =523500/ (s3+87.35s2+10470s), and the use of MATLAB to achieve the design and Simulink simulation of two kinds of PID controller, and the comparison of two kinds of PID controller. (3) result analysis, summary. The simulation results show that the control accuracy of the expert PID control is better than that of the control.
