Modeling of DC motor and its controller optimization design

In this paper, the system identification toolbox is used to identify the model of the DC motor. The identification results show that this method is simple and effective. In view of the optimization problem of the controller, an automatic optimization design method of PID parameters based on the Matlab environment is presented. This method applies active set algorithm to realize the optimization of PID parameters. The simulation results show that the method is simple, the simulated effects are ideal and the stability of the system is good.
