本文基於傳統單位回授控制系統穩態誤差的方式,利用型式數的觀念,配合Kuo針對非單位回授控制系統之穩態誤差所提出的新誤差函數來分析單位回授控制系統與非單位回授控制系統的穩態誤差。一般分析非單位回授控制系統是利用轉換的方式將其轉換成單位回授控制系統,再分析其穩態誤差;在本文中則直接使用型式數的觀念來分析非單位回授控制系統的穩態誤差,傳統判別型式數的方式是依據順向路徑轉移函數 在 處的極點數目來決定(判斷 的分母),而本文提出了新的型式數判別概念,利用函數 的零點數目來決定系統的型式數(判斷 的分子),以此方式可同時分析單位回授控制系統與非單位回授控制系統的系統型式數,故可輕易地以型式數的觀念求得系統對於不同的參考輸入信號所得出的穩態誤差值。本文的方式可連貫單位回授控制系統與非單位回授控制系統,以相同的方式來分析系統的穩態誤差,可免除必須先行將非單位回授控制系統轉換成單位回授控制系統之步驟。
This thesis is based on the method of analyzing the steady-state errors of the traditional unity feedback control systems. Combining the concept of type number and the new error function that is used to analyze the steady-state errors of nonunity feedback control systems by Kuo to analyze both unity and nonunity systems. The traditional method of analyzing the steady-state errors of nonunity feedback control systems is converting nonunity feedback control systems into equivalent unity feedback control systems. In this thesis, using the concept of type number can analyze the steady-state errors of nonunity feedback control systems directly. The traditional definition of type number is based on the Nth order poles when forward-path transfer function have at , but this thesis uses the new method of defining type number. It refers to the order of zeros of error function . Using the method can obtain type number of the systems not only unity feedback control systems, but also nonunity feedback control systems. Thus, this method can analyze the steady-state error by the same way for different systems, and the advantage of this thesis is decreasing the step to convert nonunity feedback systems into unity feedback systems.
