linear adj. 1.線的,直線的。 2.長度的。 3.【數(shù)學(xué)】一次的,線性的。 4.【動、植】線狀的;細(xì)長的。 5.由線條組成的,以線條為主的,強調(diào)線條的。 linear amplification 直線放大。 a linear equation 一次方程式。 a linear leaf 線形葉。 linear arts 線條藝術(shù)。
Secondly , as for degree reduction of interval rational bezier curves , two methods are given : pseudo linear programming method ( plpm ) and pseudo optimal approximation method ( poam ) 接下來對區(qū)間有理bezier曲線,給出兩種降階逼近算法:擬線性規(guī)劃法( plpm )和擬最優(yōu)逼近法( poam ) 。
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。
