Aiming at more effective and accurate simulation and servo-control on DC motor, the drive system of a DC motor was simulated and analyzed by applying a simulation platform SimulationX based on Modelica. Meanwhile, the position signal control was achieved through servo-control of the output rotation angle of the motor, using PID controller. In the end, the parameters of the PID controller were optimized based on OptiY, in order to improve the accuracy of the servo-control. The simulation results indicate that object-oriented model of DC motor increases the efficiency of simulation and realizes the optimization of relevant parameters for servo-control.
