And the development includes many complex and pivotal technology , such as non - linearity characteristic of dynamics and designing of non - linearity control system 而高性能的直升機的研制涉及直升機的非線性動力學(xué)特性、非線性控制系統(tǒng)設(shè)計等復(fù)雜的關(guān)鍵技術(shù)。
For this reason , the paper is aimed at the electro - hydraulic servo - system nonlinear problem , and proposes the feedback linearity means ( that is the inverse system method ) against the system mode systematically to transform such nonlinearity into the pseudo linear system . the system mode not merely continues to have system message completely feedback the linearity means , but also achieves the great limit linearization of controlled device , for designing the controller to advance system dynamic characteristic and performance index and supply the ideal terrace in the interest of the application linearity control theory 為此,本文針對該非線性問題,提出了逆系統(tǒng)狀態(tài)反饋線性化方法,將其非線性系統(tǒng)轉(zhuǎn)化成偽線性系統(tǒng),不僅完全保留了系統(tǒng)的信息,而且還實現(xiàn)了被控對象的大范圍線性化,為應(yīng)用線性控制理論去設(shè)計控制器為提高系統(tǒng)的動態(tài)特性和性能指標(biāo)提供了理想的平臺。
