Sliding Mode Variable Structure Control of Power System Chaos Based on Synchronization Thought

研究了较大周期性扰动下电力系统的分岔与混沌行为。借鉴混沌同步思想,设计了滑模变结构控制器,将混沌振荡系统同步到稳定的系统,实现混沌振荡抑制。给出了控制器推导方法,采用Lyapunov稳定性理论证明了系统的稳定性。运用Matlab进行数值仿真,结果表明所设计的控制器是有效的,能达到预期效果。

This paper analyzed its bifurcation and the chaos behavior when the power system is disturbed by a comparatively large periodic load disturbance. Based on the ideological chaos synchronization, the sliding mode controller was designed. In order to realize the chaotic vibration suppression we worked out a stably system, the controller can make the two system synchronization. The deduced method of the controller is given, the Lyapunov theory is used to prove the stability of the system . The simulation results by Matlab show that the controller is effective and can achieve the expected effect.
