摘要
提出了电力系统混沌振荡自适应控制的一种方法。电力系统混沌振荡状态和它的微分信号由微分跟随器实时提取,并通过微分跟随器对非线性周期性负荷扰动的影响进行自适应补偿。在此基础上,设计线性状态反馈控制规律,使得电力系统的运动状态保持稳定。计算机仿真验证了该方法的正确性。
An adaptive control method for chaos oscillation in power system is put forward in this paper. The states of the system and their differential signals are obtained on time by tracking differentiator, and the influence induced by nonlinear periodic load disturbance is compensated adaptively. On the basis of that, linear state feedback control law is designed to ensure the stability and security of power system. Finally, a simulation case study is given to prove the validity of the proposed method.
