| Abstract: | This paper analyzes the basic principle of the simplex algorithm,studies the mathematical model of the PID controller,designs a simplex optimization program to optimize the PID parameters with the help of Matlab,and uses the GUI design an intuitive user interface. The objective function in the optimization process decreases monotonically,indicating the PID parameter optimization is effective. The step response curve of the optimized system shows that the system＇ s static and dynamic indicators have reached the requirements and the optimization result is good. |
