基于冲击负荷扰动的自校正控制器设计

<正> 一、基差的概念 所谓基差是指某一商品在某一地点的现货价格与该商品的期货价格之差。若现货价格低于期货价格,基差为负就称之为远期升水;反之,当现货价格高于期货价格,基差为正就称之为远期贴水,这一点与外汇市场中即期汇率与远期汇率间的升、贴水相同。 一般来说,现货价格和期货价格的走势是基本一致的,但由于两个价格的变动值不完全一样,从而引起基差的变化。当正基差变大时,表示现货价格坚挺,即基差增强;反

Design of A Self-turning Algorithm for Overcome the Disturbance of Impulse Load

This paper presents a useful self turning algorithm for overcoming the disturbance of impulse load.Indentification the system modle uses the advance least squares method besed on CARMA.With the optimal moving average filter for overcoming impulse load,A advantage Generalized Predictive Control(GPC)based on the retrocession modle of h(t)is designed.From aspects of theoritical analysis and digital simulation,the self-turning controller designed features strong robustnest on rejecting impulse load.
