Based on the parameters of an actual DC motor, a discrete-time speed PI controller and a PD position controller were designed respectively by building up its model and applying a PID control system diagram purposed in this paper. Performance of the designed system was analyzed for both the cases of with and without load by simulation under Matlab/Simulink. Simulation shows that the designed controller has good dynamic performance and is robust to the change of load. Analysis and discussion are presented also concerning some issues of PID control design in real-word applications.
