| 摘 要： | 永磁同步电动机(PMSM)在某些参数及工作条件下会出现混沌运动，这将危及电机传动系统的稳定运行，因此如何抑制或消除PMSM中的混沌成为保持其稳定性的关键问题.利用微分几何控制理论，首先从解析上推导出PMSM混沌运动控制律的表达式，然后对控制过程进行仿真.理论分析及数值仿真结果表明：该控制策略不仅行之有效，而且相对其他控制方法具有一定的优越性.研究结果对保证电机传动系统的稳定运行具有较好的参考价值.

| Abstract: | Recent investigation has shown that the permanent magnet synchronous motor(PMSM) may have chaotic behaviors for cortain values of parameters or under certain working conditions,which threatens the secure and stable operation of motor-driven.Hence,it is important to study methods of controlling or suppressing chaos in PMSM.Using the exact linearization theory of differential geometry,a law of controlling chaos in PMSM is deduced in this paper, and then,the process of controlling is simulated and analyzed.Theoretical analysis and simulation results show that the deduced control law is effective and its control property is better than that of other methods.Our results may help to maintain the system's secure operation. |
