| 摘 要： | 采用交-直-交变换器对鼠笼式感应电机的电动状态进行控制,由于交-直-交变换器中间直流环节使AC/DC和DC/AC模块相互独立,AC/DC采用SPWM高频整流矢量控制,实现整流的高功率因数,DC/AC采用SVPWM空间矢量控制,以提高直流环节电压利用率,从而使感应电机获得优良的调速性能,在saber软件中对以上控制策略进行了仿真研究,仿真时采用Newton-Laphson算法及变步长仿真,仿真结果较真实的反映了感应电机的运行状况,仿真系统收敛性强,对今后研究感应电机的控制系统提供了有益参考。

| Abstract: | An AC-DC-AC converter is used to control electric state of a squirrel-cage induction motor.Because the intermediate DC link of the AC-DC-AC converter makes AC/DC and DC/AC modules independent each other,AC/DC uses high frequency rectifier vector control of SPWM to achieve rectifier high-power factor;DC/AC uses space vector control of SVPWM to increase operating factor of DC link voltage,thus making the induction motor get fine speed-regulating performance.In saber software,simulation research above the control strategy has been carried out.Newton-Laphson algorithm and variable step-size simulation have been used in the simulation.The result really reflects the induction motor running state.The simulation system has strong convergence.It will offer useful reference for studying the control system of the induction motor. |
