摘要
根据多相电机缺相运行的特点,提出了一种基于载波型SVPWM的转子磁场定向控制策略,并应用到六相电机缺相运行状态下。推导出电机不对称运行时的解耦变换矩阵,实现了定子电流的转矩分量和励磁分量的解耦,在Matlab环境下,建立六相电机缺相的转子磁场定向控制的仿真模型。仿真结果验证了该控制策略的正确性和有效性。
Based on the characteristics of multi-phase induction machine with open phase condition,a vector control scheme based on the rotor field orientation of carrier wave SVPWM is presented to be applied to the induction machine.The time decoupling transformation matrix is deduced when the induction machine runs asymmetrically,and the stator current torque component and the excitation component decoupling have been realized.The simulation model of six-phase induction machine under fault condition is established using Matlab.The simulation results verify the correctness and effectiveness of the control scheme.
