摘　　要：采用I型系统ITAE最优准则,针对跟踪阶跃响应的电液伺服系统设计了模型跟踪最优控制器,并应用Matlab进行了计算机仿真.仿真结果表明,在此种模型跟踪最优控制器控制下,电液伺服系统具有良好的动态特性.Employing ITAE optimization criterion and aimed at electrohydraulic servosystems with stepresponsetracking, an optimal controller with modeltracking is designed, and its computer simulation is also conducted with the software Matlab. It is shown by this simulation that, under the control with this controller, the electrohydraulic servosystem exhibits quite fair dynamic characteristics.
