针对液压伺服系统固有的特性和液压控制中存在的问题,提出了一种具有极点配置的广义自校正压力控制方法。它建立了液压伺服控制系统的CARMA模型,给出了模型参数的在线辨识方法和控制系统的极点配置方法。这种自适应控制方法有效地克服了系统时变及干扰对控制性能的影响,致使液压控制系统的动态性能及鲁棒性明显优于PID控制。
In view of the inherent characteristics of hydraulic servo system and the problems in hydraulic control, a generalized self-correcting pressure control method with pole configuration is proposed. It establishes the CARMA model of hydraulic servo control system, and presents the on-line identification method of model parameters and the pole placement method of control system. This adaptive control method effectively overcome the system time-varying and interference on the control performance, resulting in the hydraulic control system, dynamic performance and robustness is significantly better than the PID control.
