摘要: 要提出了微进给装置的数字PID控制及其参数的寻优控制方法,设计出了自寻优数字 PID调节控制模型.分析了微进给装置数字控制系统的影响因素,并对微进给装置控制系统相 移校正方法进行了探讨与实验分析,提出了超前输出控制相移校正方法,取得了较好的控制效 果.Abstract: A method of numerical PID control for microfeed device and an algorithm for accelerating optimization of its parameters are put forward in this paper. A model of numerical adjustment control optimized by itself is built, and the factors that affect the numerical control system are analyzed. Discussion and experiment on phase-shift correction of microfeed device show that a high correction accuracy can be obtained with the advanced output method.
