So it’s widly used in industrial drive systerm.The trigger and regulator of the DC industrial speed governing systerm are achieved by imitate circuit，which has many disadvangtage. Furthermore, the control software of digital control system can carry through logical judgment and sophisticated operation, and it has the control laws of optimality, adaptive trait, nonlinear and intelligence, which are different from the ordinary linear adjustability. In many aspects the function of digital control system has exceeded analog control system and is being used widely. In this paper, which belongs to the motor control class design. The design of the integrated use of motor learning, principle, EDA design, automatic control system and Matlab simulation technology course knowledge, design a digital DC motor speed control system schematic diagram, has prepared a detailed software process, and the use of Matlab / Simulink make simulation analysis. The design of the single chip microcomputer system commonly used a more detailed introduction, on the use of Matlab language module point mach
