一种新型的非线性积分器

A Kind of New Nolinear Integrator

提出一种新型的非线性积分器，给出它的数学模型，并用谐波线性化原理讨论它的频率特性，其幅频特性起积分作用，而相位滞后仅２７６°，高次谐波分量小，抗干扰能力强．应用这种积分器设计了一个双目标优化的二次优化系统．仿真结果表明，系统的控制性能好，具有广泛的应用前景．

It provides a kind of new nonlinear integrator and its mathematical model.Its frequency responses is disscussed by the harmonics Linearization method.Its phase Lag is found to be only 27 6°,All high order harmonics are very small,And it is very resistant to disturbances.By Using it,an two-objective optimum control system is designed.It has very good control performances and will have good prospects in application.
