In order to achieve the purpose of two-dimensional correction, a hardware system with digital signal processor as the main controller is designed. The main controller is selected as digital signal processor (DSP) in the design, the model is TMS320F28335, and it is used with photoelectric code disk and full bridge control. The research background and development status of the correction system are introduced. Through the actual correction requirements and system structure, the main control chip, motor control, encoder and other functional modules in the control system are introduced respectively, and the motor control scheme is designed to realize the miniaturization of the control system circuit, which can satisfy the requirements of small size, low cost and low power consumption.
