摘要
建立了考虑转子永磁体磁链和定子电感谐波分量的表贴式永磁同步电机数学模型,对其进行简化分析处理.基于理论分析法,对三相反电势(counter electromagnetic force,EMF)测量值进行快速傅立叶变换(fast Fourier transformation,FFT)分析,得到三相反电势谐波分量,用以计算dq轴上的转子磁链6次和12次谐波分量幅值;在此基础上,设计基于Lyapunov稳定性理论的状态观测器对dq轴上的定子自感和互感6次谐波分量幅值进行辨识.实验结果验证了本文谐波参数辨识算法的有效性和实用性.
Mathematical model of surface mounted permanent magnet synchronous motor considering the harmonic component of permanent magnet flux and stator inductance is established,then it is simplified.Based on the theoretical analysis method,three-phase counter electromagnetic force(EMF)measurement is analyzed by fast Fourier transformation(FFT),and the harmonic component of three-phase counter EMF is obtained.Then it is used to calculate the sixth and twelfth harmonic component of rotor flux on dq axis.On this basis,a state observer based on Lyapunov stability theory is designed to identify the sixth harmonics of stator self inductance and mutual inductance on dq axis.Experimental results verify the effectiveness and practicability of the harmonic parameters identification algorithm in this paper.
