【摘要】 介绍了PMAC运动控制器中PID的控制原理,并对基于其上的数控试验台的PID参数调节进行了说明。利用PMAC自带的PID程序,通过对阶跃信号和抛物线信号响应图像的分析,整定了系统参数,使试验台获得良好的动态特性。更多还原

【Abstract】 This paper introduced PID control principle of PMAC motion controller and stated a method of PID parameters adjustment of NC test bench based on PMAC. Analyzed system response curves after the step signal and parabolic signal are inputted by using PID executive program of PMAC adjusted the PID parameters and making the test bench has a better dynamic performance.更多还原
