一种低成本电路设计在伺服控制系统中的应用

An Application of Low-cost Circuit Design in Servo Control System

本文介绍了一种基于DSP和分立驱动电路的伺服控制电路设计方案,通过优化电路设计,实现低成本设计,既能满足控制精度、响应速度等性能要求,又控制了体积.系统采用TMS320F2812型DSP为主控单元,以最简单的方式配置外围电路;算法上采用带有前馈补偿的PID的控制方式,通过脉宽调制实现对有刷电机的控制.

This paper presented a servo control design based on DSP and the discrete drive circuit. By optimizing the circuit design, this low-cost scheme can satisfy the specification performance for accuracy and response time, which also limits the circuit size. The corresponding system, in which the DSP of TMS320F2812 is used as the main control unit, is equipped with the simplest periphery circuits. Using the PID control with feed forward compensation as its algorithm, the controller accomplishes the brush motor control with pulse-width modulation.
