| 摘 要： | 给出了内置式永磁同步电机直接转矩控制系统定子磁链幅值、转矩角和转矩的简化控制规律,提出了一种适用于转矩角小于90°时的内置式永磁同步电机直接转矩控制电压矢量选择策略,并针对Honda Civic06My Hybrid混合动力电动汽车用15kW内置式永磁同步电机进行实验验证。实验结果表明:相比较于开关表控制,电压矢量选择策略可有效减小电流和转矩脉动,电流谐波含量小且固定开关频率。

| Abstract: | Simplified control principles of stator flux,torque angle and torque of interior permanent magnet synchronous motor(PMSM) direct torque control(DTC) system were given.Voltage vector selection strategy of interior PMSM DTC system which is suitable for the torque angle less than 90° was proposed.Experimental results for a 15 kW interior PMSM used in Honda Civic 06My Hybrid electrical vehicle were proposed.Experimental results show comparing with the switching table,voltage vector selection strategy can decrease current and torque ripples and fix the switching frequency. |
