摘　　要：由于二次调节静液传动系统在工作过程中受死区、滞环、库伦摩擦等因素的影响,属于典型的非线性系统,采用常规控制,很难取得令人满意的效果。针对二次调节系统的非线性特征,在已有成果的基础上,应用Hamiltonian泛函方法,构建了二次调节静液传动系统的Hamiltonian形式,设计了基于观察器的鲁棒控制器,应用到二次调节静液传动速度控制系统中,并进行了仿真研究,取得了良好的控制性能。仿真结果表明:系统的动态特性明显得到了改善,具有较强的抗干扰能力和良好的鲁棒性。Because the secondary regulation transmission system has the factors such as deadzone,hysteresis loop,coulomb friction,it is a typical nonlinear system.It is difficult to obtain famous control effect by use of conventional control method.Based on observer-based method,the application of Hamiltonian function method is studied in a secondary regulation rotate speed systems with the state being not completely measurable.The Hamiltonian form of the secondary regulation hydrostatic transmission system was constructed and a robust observer-based controller was designed,and several results on the asymptotic stability and observer-based robust control problems were presented.The observer-based robust controller has been applied to the secondary regulation transmission speed control system,and the performance simulation has been conducted.The simulation results show that the dynamic characteristics of the system have been improved significantly,with strong anti-interference ability and good robustness.
