电-气比例/伺服控制系统的最优状态反馈控制研究

Abstract

Abstract: A design method with LQ (linear quadratic index) principle is introduced into electro-pneumatic proportional and servo control system to obtain an optimum static feedback controller for the system. The authors use a special scheme to determine the LQ index, that is, to choose a suitable LQ index so that the closed-loop system can achieve a significant feature i. e. a desired assignment of the dominant poles.The feasibility of the method is confirmed by the results both of simulation and experiments.

Key words: control system, optimum control, servo pneumatics
