水轮机调节系统最优鲁棒极点配置调速器的设计

The Design of Optimal Robust Pole-placement Governorfor Hydraulic Turbine Regulating System

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。

Pole_placement is an effective method for controller design, especially for nonminimum_phase system. But the controller designed with this method doesnt have better robustness for non_linear and time_varying system, so its application is limited.This paper presents a new method of optimal robust pole_placement using the theory of dynamical interval, and apply it to design robust controller of hydraulic turbine regulating system. The results of simulation proved that the closed_loop system has a better robustness while the parameters of plant vary throughout their respective intervals.
