摘要
针对大行程电磁驱动微纳米定位技术控制精度较低的问题,根据电磁驱动装置的工作原理,提出优化PID的控制方案,并在Matlab软件中搭建控制系统的Simulink模型.相较传统PID控制,对前馈PID和模糊PID算法的改进效果进行研究,得出前馈PID拥有较好的动、静态控制性能,模糊PID鲁棒性较佳的结论.
Aiming at the problem of low control precision of large stroke electromagnetic drive micro-nano positioning technology, an optimized PID control scheme was proposed. According to the working principle of the electromagnetic drive device, the Simulink model of control system was established and built in Matlab software. Comparing with traditional PID control, the improvement effects of feedforward PID and fuzzy PID algorithm were studied. It is concluded that feedforward PID has better dynamic and static control performance, and fuzzy PID has better robustness.
