绝对误差积分 meaning in English

integral of absolute value of error

This paper first analyzes performance criteria of a control system , and proposes a controller design method that incorporates disturbance attenuation and robust performance . the robust pid controller design amounts to an optimization problem with a non - convex constraint . genetic algorithm is used to solve the problem due to its global search ability , simulation examples show that the method is effective and have general sense
本文从分析控制系统的性能指标入手，从抗干扰性能和鲁棒性能两方面综合考虑控制器的设计，得到一种鲁棒pid控制器的设计思路，把pid控制器的设计问题转化为求解一个带鲁棒性能约束的绝对误差积分指标( iae )优化问题。
