在PID控制中，微分信号的引入可改善系统的动态特性，但也易引起高频干扰。在误差扰动突变时尤其显出微分项的不足。若在控制算法中加入低通滤波器，则可使系统性能得到改善。(In PID control, the introduction of differential signal can improve the dynamic characteristics of the system, but it can also cause high-frequency interference. When error perturbations change abrupt, the deficiency of differential terms especially shows. If the low-pass filter is added to the control algorithm, the performance of the system can be improved.)
