【摘要】 为了模拟基于三电平逆变器驱动的磁浮列车用的直线同步电机的性能,并检验三电平逆变器所用的空间矢量脉宽调制(Space Vector Pulse Width Modulation,简称SVPWM)方法和电气参数的正确性,文中利用动子磁场定向控制、坐标变换、空间矢量控制技术建立了TR08磁浮列车的驱动控制系统模型。最后得出的仿真结果与技术资料所提供的数据基本吻合,从而证明了所建立的磁浮列车驱动控制仿真模型的正确性和有效性。更多还原

【Abstract】 The Linear synchronous motor used in Maglev vehicle is supplied by three-level inverter.Control strategy of Space Vector Pulse Width Modulation(SVPWM) applied to three level inverter is discussed in detail.To verify the validity of the electric parameters and to simulate the motor performance,propulsive control model of TR08 Maglev vehicle was constructed.The propulsive system model of Maglev vehicle was constructed by rotor-oriented control,coordinates transformation and the space vector control.In the end,a series of simulative results are given.The results are consistent with the technical data,and the validity of the propulsive system model is confirmed.更多还原
