摘要
Abstract
To avoid high frequency noise,the traditional asynchronous motor speed current double-closed-loop system was used by PI regulator as its speed and current regulator.When speed was required to track reference signal quickly and inertia of motor was large,the hysteresis effect of triditional PI retulator would give rise to overshoot and oscillation of speed loop.Feedback control couldn't eliminate contradiction between rapidity and stability.Feedforward control could realize complete compensation,extend bandwidth of system largely and avoid contradiction between rapidity and stability.Feedforward control based on nonlinear tracking differentiator inroduced could be used in servo system which was hard on tracking performance.关键词
