Sivakumar K. Gopakumar Indian Institute of Science Induction Motor IM: Induction Motor 感应电机（异步电机） Sensor Sensorless：无速度传感器 Sensor: 有速度传感器 PG(Pulse Generator)：编码器 VC or FOC Hysteresis Controller Estimation Equations Conclusion The present sensorless vector control scheme eliminates requirements of terminal voltage sensing for entire speed operation up to six-step mode. appropriate device on-state drops are compensated to achieve a steady-state operation up to less than 1 Hz Experimental results show that the proposed sensorless drive, with good dynamic performance and smooth operation extending up to six-step mode, can be considered as a replacement to the conventional general-purpose V/f control drive.
