误差积分 meaning in English

error integral

4 . in order to solve the chattering brought about by structure variant of controller , a design method of dynamic sliding mode in ac servo system is proposed . the control signal produces an effective chattering reduction after integrations , and the addition of the tracking error integration can eliminate the steady - state error
4 、为解决传统变结构控制的抖动问题，本文采用动态滑模变结构方法，利用输出的积分特性消除抖动，同时加入误差积分项改善系统的稳态误差。
