永磁同步风力发电机中混沌运动的控制

摘要

针对永磁同步风力发电机系统中的混沌现象，用最优控制方案，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，也为研究优良的控制方法提供了理论参考。%To deal with the chaos in the permanent magnet synchronous generators(D‐PMSG) ,this pa‐per adopted the optimal control strategies to make systems disengage chaos and operate more stably .First‐ly ,it demonstrated that the chaotic behaviors occurred under certain working conditions with model param‐eters .Then a simple and optimal controller was designed based on the optimal control theory .Finally ,the simulation results verified the correctness of the theoretical analysis and provided the theoretical reference for the further study on improving the control performance .
