摘　　要：首先将无刷直流电机变换为类似Lorenz混沌方程,在特定参数条件下从相位图、分岔图和Lyapunov指数分析了其混沌特性,其次,针对含参数不确定和外部干扰的混沌系统设计了时延估计控制器,并基于Lyapunov稳定性原理证明了系统的全局渐进稳定性,最后进行了MATLAB数值仿真验证。Brushless DC motor is transformed into a similar Lorenz chaotic equation,and the chaotic characteristics are analyzed from the phase diagram,the bifurcation diagram and the Lyapunov stability theory under certain parameters.For the chaotic system with parameter uncertainty and external disturbance,the time-delay estimation controller is designed,and the global asymptotic stability of the system is proved based on the Lyapunov stability principle.Finally,the MATLAB numerical simulation is used to verify the feasibility of the method.
