摘　　要：研究推力矢量电液位置伺服系统的模型参考模糊自适应控制.这类系统存在着参数变化和加性扰动,为解决这一类非线性的控制问题,引入模型参考模糊自适应机构,构成模型参考模糊自适应控制(MRFAC).与传统的PID相比,该方法提高了推力矢量电液位置伺服系统阻尼比,改善了系统的动态性能,并且可以有效抑制参数变化及外力扰动,具有很强的鲁棒性.Electro-hydraulic position servosystem of thrust vector by using model-reference fuzzy adaptive control was investigated. In a system of this kind, there is parameter variation and additive disturbance. In order to deal with this class of nonlinear control problem, a mechanism of model-reference fuzzy adaptation was introduced to constitute the model-reference fuzzy adaptive control strategy （MRFAC）. Compared with the traditional PID strategy, this approach could improve the damping ratio of the proposed control system and the dynamic characteristics of system as well. Besides, it could effectively restrain the parameter variation and external disturbance, having a strong robustness.
