precise positioning system
解釋
精密定位系統-
In the positioning servo - system, which generally is configured by the d. c. pulse width modulator ( pwm ) velocity governing system and position servo - loop, the parameter perturbance of pwm velocity loop really exist by reason of such as the load behavior ; power voltage supply ; operating setting value, etc. 1, 2 ， and it cannot be ignored. by using the identification technique to form the mathematical model of the system, authors have confirmed the facts. therefore, to design the discrete sliding mode controller ( dsmc ) of the positioning servo - system, the perturbed parameters value bounds of the pwm velocity loop, which is as the controlled plant of position servo - loop, should be accounted. consequently, the design principle of dsmc for accounting system with parameter perturbance is proposed by the authors. the proposed method can ensure the stability of system with parameter perturbance and the behavior of non - overshoot, fast precise positioning. in order to reveal the effects of the design method, the comparative research work is done by the authors. also, it has been tested in an industrial experiment, the results proved it is satisfactory
由直流脈寬調速系統（ pwm ）和位置環構成的定位系統中，速度環的參數隨負載特性；電網電壓；給定工況而攝動是不容忽視的.作者通過系統辨識建模也證實了這一事實1 ， 2 .因此在設計位置環的離散滑模控制時，必須針對速度環（即位置環的控制對象）的參數攝動范圍採用「對象參數攝動離散滑模控制器的設計方法」 ，以確保系統在參數攝動時的穩定性和快速、無超調、準確定位的優良動態品質.為剖析該設計方法的控制效果，本文作了對比性研究，並將該設計方法用於工業試驗中，取得了滿意的結果 -
