Analysis and Control of Chaotic System in permanent Magnet Synchronous Generators for Wind Power

鉴于直驱式永磁同步风力发电机(D-PMSG)在运行启动或停机时存在混沌振荡现象,这对整个系统及工作状况将产生不利影响。提出了用最优控制,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。基于最优控制理论,提出了一种控制器,该控制器不仅简单而且易实现。仿真结果验证了理论分析的正确性,以及对研究优良的控制方法提供了理论参考。

In this paper, In view of the appearance of chaotic behavior in permanent magnet synchronous motor（ D-PMSG）, the optimal control strategy is presented ,which makes systems disengage chaos and operate stably. Also, the chaotic behaviors or limit cycle phenomena is demonstrated under certain working conditions or the parameters of the model having a certain range of val- ues. Optimal controller is designed based on the Optimal theory for systems. This controller is not only simple but also can validity. Also, The simulation results confirm the correctness of the theoretical analysis of the proposed method, besides, the research results will be provided as theoretical references for the study of improving control performance.
