What the model of DSP we chose is TMS320F28335, which is developed by the company of TI. Our main purpose is to research the whole process of how this controller can control the dc servo motor. The structure we used to write this paper is the From whole to part. It means, at first, we will analysis the whole control system comprehensively. And then, we will study each module of this controller separately.The focus of this paper is that the motors drive module be inputed by the PWM which is produced by DSP. And it makes the motor to running normally. The Modules which is used for this system, such as: Motor drive module, photoelectric encoder module, photoelectric isolation module, Holzer current sensor module, power module, the chip of DSP, and so on. After simulation and debugging, the result is meet the design standards. From the design guide, we choses the rated voltage of the motor is 110V, the rated power is 185W, and the rated speed is 1800 rpm. When the operating parameters of the motor are out of order, after PI adjustment, the feedback control systems can correct the operation of the motor rapidly; The motor is switched off when the duty cycle of the PWM wave is 0.5. When larger t
