本文首先給出了Butterworth 標(biāo)準(zhǔn)傳遞函數(shù)，然后提出了一種設(shè)計(jì)狀態(tài)反饋系統(tǒng)的方
法，該方法包括：利用線性變換將能控系統(tǒng)化為能控標(biāo)準(zhǔn)形，使能控標(biāo)準(zhǔn)形系統(tǒng)的閉環(huán)傳遞函數(shù)等于Butterworth 標(biāo)準(zhǔn)傳遞函數(shù)，通過比較法來求得能控標(biāo)準(zhǔn)形系統(tǒng)的狀態(tài)反饋增益陣，再通過變換得到一般能控系統(tǒng)的狀態(tài)反饋增益陣。設(shè)計(jì)示例表明該方法設(shè)計(jì)的狀態(tài)反饋系統(tǒng)具有良好的階躍響應(yīng)特性。
關(guān)鍵詞：Butterworth 標(biāo)準(zhǔn)傳遞函數(shù)；能控標(biāo)準(zhǔn)形；狀態(tài)反饋；設(shè)計(jì)

Abstract: In this paper, Butterworth standard transfer functions are firstly given, and then a method of designing state feedback system is proposed. The method includes: making use of the line transformation the controllable system changes into controllable standard form, making the closed-loop transfer function of controllable standard form system same as Butterworth standard transfer function, passing compare the gain matrix of state feedback is
solved, then passing transformation the gain matrix of general controllable system is got. The example indicates the step response of the state feedback system is good.
Key words: Butterworth Standard Transfer function；controllable standard form；state feedback；design
