摘要
采用微分几何方法,对一类含确定扰动的简单电力系统的混沌行为进行控制研究。研究内容主要包括:系统模型的可精确化条件验证、模型精确线性化处理和基于最优二次型方法的电力系统混沌控制器设计。仿真结果显示:加入控制器后,系统混沌振荡得到消除,稳定运行在平衡点状态。研究表明:采用微分几何方法能够对电力系统的混沌行为进行有效控制,控制效果与其他混沌控制方法相比,具有明显的优越性。理论分析和数值仿真结果都证明了该控制方法的有效性。
In this paper the method of controlling chaos in the power system with decided periodic perturbation is studied based on the differential geometry method including verification of exact linearization condition of the non-linear model system,disposing for exact linearization and designing controller to restrain chaos of the system.The simulation results show that the chaotic oscillation of system can be eliminated after adding the controller and the system runs on equilibrium point.The analysisresults show the differential geometry method is effective for controlling chaos of power system and its control property is better than that of other methods.
