摘　　要：研究了切换双机电力系统的鲁棒控制器设计问题.首先,考虑到实际系统中的不确定性对系统性能的影响,建立了切换双机电力系统含有不确定性的数学模型.然后,利用公共Lyapunov函数方法,给出了系统控制器的设计方案,并证明了闭环系统是稳定的.最后,总结了本文的工作并指出了今后将进一步探索的问题.This paper considers the robust controller design issue of two-machine power systems. First, considering the impact of uncertainties on dynamics of power systems, a mathematical model including uncertainties for two-machine systems is proposed. Then, by means of the method of common Lyapunov function, the control schedule is provided, and the stability of closed-system is verified. Finally, a conclusion is given to summarize the current paper and to point out some important topics deserving investigation in the field.
