摘　　要：针对电-液伺服机构时变性、非线性的特性,采用参考模型自适应控制,并进行了计算机仿真,再现了系统单位阶跃响应和系统的跟踪性能。仿真结果表明:采用参考模型自适应控制的电液系统具有良好的动态性能。The model reference adaptive control （MRAC） method was used to improve the nonlinear and time varying characteristics of electro-hydraulic serve system. Computer simulation was done, the step response and track following characteristics of the system were reproduced. The simulation result proves that the MRAC method has better dynamic characteristic.characteristic
