在研究泵控马达电液伺服系统的自适应控制中，提出了一种分三阶段实施的模糊控制策略，并进行了大量实验研究，结果表明，该方法克服了模糊控制的不精确性和易振荡性，且在相当宽的惯性负载情况下，系统的特性都是令人满意的。文中说明了三段式模糊控制的基本原理，并给出了其用于泵控马达电液伺服系统的实验结果
In the study of adaptive control of pump-motor electro-hydraulic servo system, a fuzzy control strategy implemented in three phases is proposed, and a large number of experimental studies are carried out. The results show that this method overcomes the inaccuracy of fuzzy control Oscillatory, and the system’s characteristics are satisfactory with a fairly wide range of inertia loads. The paper describes the basic principles of three-stage fuzzy control, and gives its experimental results for the pump-motor electro-hydraulic servo system
