带干扰的切换双机电力系统鲁棒控制器设计

Robust Controller Design for Switched Two-machine Power System with Disturbance

针对带干扰及系统参数不确定励磁控制的切换双机电力系统的鲁棒控制器设计问题,首先建立系统的数学模型,然后利用公共Lyapunov函数方法和H∞控制,实现系统切换控制器的设计,得到了带干扰切换双机电力系统在任意切换下的渐近稳定性的结果。因而,电力系统中遇到紧急情况需要退出或者增加1台发电机时,该切换过程系统都保持稳定,并通过仿真进行了验证。

For systems with uncertain parameters with interference and robust controller design problem excitation control switch dual-power system, first, the mathematical model is established, and then, by using public Lyapunov function and H？ control, the result of the asymptotic stability of the switched two-machine power system with the disturbance is obtained. Thus, when to exit is needed or a generator is added in the event of an emergency situation in the power system, the whole switching system is stable and it is verified by simulation.
