Optimal Design of PID Parameters of a Typical Second-Order System by Simplex Method
Aiming at a typical second-order system,a PID parameter optimisation design method based on the simplex method is proposed.By establishing and analysing the objective function,the PID controller is introduced into the system,and then the PID parameters are optimized by using the simplex method to obtain the optimal parameter combinations to optimize the stability and performance of the system.The experimental results show that the optimal parameters obtained by the proposed simplex method can effectively improve the control performance of the second-order system and have certain practical value.
