汽轮发电机主汽门开度非线性鲁棒控制

Nonlinear robust control for turbine main steam valve

由于外界干扰以及各种故障的影响,电力系统的结构并不是不变的,因此其中的一些重要参数,如输电线路电抗等,总是包含某种不确定性。针对含有参数不确定性的汽轮机调速系统,使用自适应逆推方法及Lyapunov方法设计了非线性鲁棒汽门控制器,基于该方法的设计,设计过程系统、简明,且不必对原系统进行线性化,通过对单机无穷大系统的仿真表明了该控制器的有效性。

Owing to the influences of external disturbances and a variety of faults, the configuration of power systems is not constant enough, so that such major parameters as reactance of transmission line always contain a few uncertainties. For the turbine speed governor system with parameter uncertainties, the nonlinear steam valve robust controller is designed using adaptive backstepping and Lyapunov methods. Thanks to these methods, the design procedure turns out to be systematic and concise, and the origin system need not be linearized. The simulation results show the effectiveness of this controller.
