【正文】 能穩(wěn)定，因此系統(tǒng)的抗干擾能力往往顯得十分重要。簡(jiǎn)言之，調(diào)速系統(tǒng)的動(dòng)態(tài)指標(biāo)以抗干擾性能為主，隨動(dòng)系統(tǒng)的動(dòng)態(tài)指標(biāo)以跟隨性能為主?？刂葡到y(tǒng)的數(shù)學(xué)模型是描述系統(tǒng)內(nèi)部物理量（或變量）之間關(guān)系的數(shù)學(xué)表達(dá)式。時(shí)域中常用的數(shù)學(xué)模型有微分方程、差分方程和狀態(tài)方程；復(fù)數(shù)域中有傳遞函數(shù)、結(jié)構(gòu)圖；頻域中有頻率特 。 關(guān)鍵字：隨動(dòng)系統(tǒng) 性能分析 ４ digest Servo system is to point to the output of the system with a certain the precision and speed of tracking input of the automatic control system, and is the input of random, unpredictable. In many cases, servo system special was charged with volume is mechanical displacement control system than also. Control the development of technology, make servo systems have been widely used. Position servo system is feedback control system, is the closedloop control and speed regulation system for the quantitative value is constant, want to output quantity can stable, so the antiinterference ability of the system often bee very important. And with the position of the position servo system instructions are often changes, requirement output accurate quantitative change to follow, the response of the output, flexibility and accuracy position servo system became the main features. In short, speed regulation system in dynamic index to antijamming performance is given priority to, servo system dynamic index to follow performance primarily. In the control system of the analysis and design, the first to establish the mathematical model of the system. The mathematical model of the control system is to describe the system internal parameters (or variables) of the relationship between the mathematical expressions. In automatic control theory, the mathematical model has a variety of forms. Commonly used in time domain of mathematical model of the ordinary differential equations, difference equation and state equation。 A frequency characteristics in the frequency domain. This course of study is designed with the position of the lag of actuator system calibration, and carries on the analysis.
