摘要
采用自适应控制方法对永磁同步电机混沌系统进行控制研究,当该混沌系统参数未知时,基于Lyapunov稳定性理论,设计了相应的控制器和参数自适应律,使系统的状态控制到任意一个不稳定平衡点,并运用Barbalat引理,在理论上证明了受控系统的渐进稳定性,从而消除了混沌,仿真结果证明了该方法的有效性.
The adaptive control method was adopted to control chaos in permanent magnet synchronous motor system. When parameters of the chaotic system are unknown,the corresponding controller and adaptive law of parameters are designed to suppress the state of the system to any unstable equilibrium based on the theory of Lyapunov stability. And using Barbalat lemma,the asymptotic stability of the controlled system is proved theoretically. Then the chaos was eliminated. The simulations show that the method is effective.
