在某些参数作用的情况下,永磁同步电机(PMSM)会出现混沌现象。利用反推Backstepping同步控制原理,可以使受控的混沌系统逐渐退化为稳定的系统,依据李雅普诺夫稳定性原理证明所设计的控制器可使得二个结构相同但参数不同的混沌系统逐渐达到同步。仿真结果进一步验证了该方法的有效性,对电机运动的稳定性具有较好的参考价值。
In some parameters, permanent magnet synchronous motor (PMSM) would appear the chaos phenomena. By using Backstepping self synchronous control principle, the controlled chaos system would gradually degenerate to stable system, and the author designed the Backstepping controlled based on Lyapunov stability, the Lyapunov principle is proved that the designed controller can make two of the same structure but different parameters of chaotic systems gradually achieve synchronization. The simulation results further demonstrate the effectiveness of this method, the stability of the movement of motor has a good value.
