提出了一种对并网绕线转子感应电机的扭矩和磁通进行快速响应控制的方法，该电机由转子侧背对背连接的电压源逆变器供电。它基于电网侧有功功率和无功功率的测量，其中电压和电流以固定频率交变。使用磁滞控制器使有功功率和无功功率跟踪参考值。该方法无需转子位置传感，并且具有出色的动态性能，如变速恒频感应发电机系统的仿真和实验结果所示。它还能够即时启动。因此，对于驱动器和发电机应用来说，它是一种有吸引力的无传感器控制方法。
A method is presented for fast response control of the torque and flux of a grid connected wound rotor induction machine fed by back to back connected voltage source inverters on the rotor side. It is based on the measurement of active and reactive power on the grid side where voltages and currents are alternating at fixed frequency. The active and reactive powers are made to track references using hysteresis controllers. The method eliminates the need for rotor position sensing and gives excellent dynamic performance, as shown by simulation and experimental results from a variable speed constant frequency induction generator system. It is also capable of starting on the fly. It is thus an attractive sensorless control method for drive as well as generator applications.
