Firstly, the mathematical model of DC motor is introduces, and the three methods of its speed regulation are given, and the method of changing the armature voltage is chosen as the method of its speed regulation. Then the working principle of DC speeding system for four-quadrant chopper control is analyzed in detail, and the models is established based on Matlab/Simulink, and the simulation results are given. Through the analysis of simulation results, the simulation results are consistent with the theoretical analysis, and the correctness of theoretical analysis and modeling simulation of DC speed control system for the four-quadrant chopper control is verified. Finally, the advantages of DC speed control system for the four-quadrant chopper control are highlighted by comparing the simulation results with the other two kinds of chopper DC drive system.
