一、前言文献[1]提出了一种相角滞后等于零的非线性积分器,本文发现用该积分器控制惯性对象时,不能消除稳态偏差,实质上起不到积分器的作用。为此,本文参考文献[1] I. Preface [1] proposed a non-linear integrator with phase angle lag equal to zero. This paper finds that when using the integrator to control inertial object, it can not eliminate the steady-state deviation and can not substantially reach the function of integrator. To this end, this reference [1]
