摘要
针对同步磁阻电机系统中的混沌现象,提出了用自适应控制,使系统脱离了混沌,运行稳定。首先,验证了在某些参数与工作条件下系统会出现非常复杂的混沌运动。基于Lyapunov稳定性理论,提出了在系统已知参数与未知参数下的自适应控制器,该控制器克服了以往一般自适应控制器中空置率不连续的缺点。仿真结果验证了理论分析的正确性,对研究优良的控制方法提供了理论参考。
Aiming at chaos in the system of synchronous reluctance motor,an adaptive control method has been proposed to keep the system free of chaos and running smoothly.First,the system has been verified to have some complex chaotic motions under certain parameters and working conditions.Based on Lyapunov stability theory,the adaptive controller is proposed for the system with known and unknown parameters which will overcome the shortcoming of discontinuous vacancy rate in the previous adaptive controllers.Simulation results verify the correctness of theoretical analysis.It also provides a theoretical basis for the study of excellent controlling.
