复合误差反馈δ-MRAC控制器及其在电液伺服系统中的应用研究

STUDY ON COMPOUND ERROR-FEEDBACK ADAPTIVE CONTROLLER WITH S- MRAC CONTROLLER AND ITS APPLICATION IN HYDRAULIC SERVO SYSTEM

提高系统鲁棒性是自适应控制系统亟待解决的控制问题,根据δ-MRAC控制理论,构成δ变换的复合误差反馈数字自适应控制器,并应用于电液伺服系统中,通过大量的仿真试验研究,说明这种控制方法具有较高的鲁棒性和较强的适应性。

System robustness is a research focus of adaptive control system, according to the S -MRAC scheme, a kind of compound error-feedback numeric adaptive controller is introduced in the dissertation, which is used in hydraulic servo system and its robustness and adaptive character were well proved through lots of simulation and experiment.
