摘要
从矢量空间解耦的观点出发,采用推广派克变换建立了五相永磁同步电机的数学模型,并分析了推广派克变换矩阵的特点。其结论为多相电机控制策略的研究,特别是多相PWM技术的研究提供了依据。仿真结果验证了方法的有效性,并指出了传统SVPWM方法在多相电机驱动系统中的不足。
Based on the point of view of vector space decomposition,the generalized Park＇s transformation to build up the mathematic model of five - phase PMSM are adopted, and the characters of this transformation are analyzed in detail. The conclusion is very useful for the research of multi -phase machines control, especially for the research of multi - phase PWM. Simulations verify the validity of this method and indicate the drawback of conventional SVPWM.
