high order harmonics
解釋
高次諧波-
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,給出它的數學模型,並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.應用這種積分器設計了一個雙目標優化的二次優化系統.模擬結果表明,系統的控制性能好,具有廣泛的應用前景 -
The widely applications of nonlinear instruments have produced many high order harmonics, they are flowing into the power network and greatly influence the quality of electric power. and the frequency is n ' t constant but changed around 50hz
電網中非線性設備的使用日益增多,所產生的高次諧波電流大量注入電力線路中,使得電網電壓、電流波形發生畸變,同時電網頻率並不是固定不變的,而是在50hz附近波動。
