摘要
在一定参数条件下永磁同步电机会出现非线性混沌行为,主要表现为转矩、转速振荡等,导致系统性能不稳定。为此,在实际电机平台上进行滑模控制SMC(slidemodelcontrol)实验,通过合理的方法处理数据后,绘制相应的系统相图并与无滑模控制作对比,从另一角度验证了混沌现象。在永磁同步电机混沌运动分析模型的基础上,利用稳定性理论和平衡点性质在理论上研究永磁同步电机的混沌动态行为。实验结果与数值仿真一致,验证了混沌现象的存在性及此理论分析的正确性,同时,表明滑模控制对混沌现象具有较优的抑制作用。
Under certain parameters,a permanent magnet synchronous motor( PMSM) will exhibit nonlinear chaotic behavior,which is mainly manifested in torque and speed oscillation,resulting in unstable system performance.Under this background,a sliding mode control( SMC) experiment was carried out on an actual motor platform.After a reasonable process of data,the corresponding system phase diagram was drawn,and it was compared with that without SMC,thereby verifying the chaotic phenomenon from another point of view.Based on the analysis model of chaotic motion of PMSM,the chaotic dynamic behavior of PMSM was studied theoretically by using the stability theory and equilibrium point properties.It was found that the experimental results were consistent with the numerical simulation,which verifies the existence of chaos and the correctness of theoretical analysis and shows that SMC has a better inhibitory effect on the chaotic phenomenon.
