一种基于模糊补偿的自适应控制在液压转台中的应用

 针对仿真转台电液伺服系统的非线性特点,提出了一种基于模糊补偿的自适应控制方法。该方法把实际系统看成是由线性和非线性两部分所组成,对线性部分采用基于精确数学模型的控制方法,而对非线性部分主要采用以模糊自适应补偿为主的控制方式。为了提高模糊自适机构的补偿效果,采用了规则可调整的模糊控制器,仿真结果表明,该方法具有较高的控制精度和鲁棒性能。

Application of Adaptive Control in Hydraulic Simulator Based on Fuzzy Compensator

This paper presents an adaptive control based on the rule adaptive fuzzy compensator according to the electrohydraulic servosystem's nonlinear characteristic in the simulator. This approach is based on the fact that the servosystem consists of a linear part and a nonlinear part. The former can be controlled according to its mathematical model, and the latter is mainly controlled by the rule adaptive fuzzy control. The simulation shows that the proposed approach can achieve an accurate and robust performance.
