极点配置方法是一种有效的设计调速器的方法 ,特别适用于非最小相位系统的设计。但对于非线性和时变系统 ,这种方法鲁棒性较差 ,其应用也就受到限制。本文应用动态区间系统最优鲁棒极点配置方法 ,对常规极点配置方法进行了改进 ,并应用于水轮机调节系统的最优鲁棒控制器的设计。仿真试验表明 ,当对象参数在其各自的区间变化时 ,闭环系统具有一定的鲁棒性。 The pole placement method is an effective method of designing a governor and is particularly suitable for the design of non-minimum phase systems. However, for nonlinear and time-varying systems, the robustness of this method is poor and its application is limited. In this paper, the optimal pole placement method of dynamic interval system is applied to improve the conventional pole placement method and to design the optimal robust controller for turbine governing system. Simulation results show that the closed-loop system has a certain robustness when the object parameters change in their respective sections.
