| 摘 要： | 在要求高速、快响应的交流伺服定位系统中,采用传统PID控制很难实现高速定位.为解决此问题.在设计出包括位置环、速度环和电流环的三闭环PID伺服控制系统的基础上,引入电流环和速度环的前馈控制来提高定位控制的性能.通过仿真验证了前馈控制在指令信号跟踪方面的良好效果,然后设计出实验系统,进行了与普通PID伺服控制系统的对比实验.结果表明,引入前馈控制的PID伺服控制系统可以实现交流伺服系统的高速定位控制.

| Abstract: | Using traditional PID control strategy is hard to achieve high-speed positioning in ac servo system.To solve the problem,it introduces the current feedforward and speed feedforward into the PID control servo system including position/speed and current loop.The simulation validates the perfect effect of feedforward control in instruction signal tracking,and a comparing experiment is carried out between the experiment system and common PID servo control system.The experiment results indicate the PID servo con... |
