Abstract : 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 文摘:提出一種新型的非線性積分器,給出它的數(shù)學(xué)模型,并用諧波線性化原理討論它的頻率特性,其幅頻特性起積分作用,而相位滯后僅27 . 6 ,高次諧波分量小,抗干擾能力強(qiáng).應(yīng)用這種積分器設(shè)計(jì)了一個(gè)雙目標(biāo)優(yōu)化的二次優(yōu)化系統(tǒng).仿真結(jié)果表明,系統(tǒng)的控制性能好,具有廣泛的應(yīng)用前景
