Vector Control of Induction Motors without Speed Sensor

本文提出了一种无速度传感器的感应电动机矢量变换控制方案，在理论上进行了推导，给出了仿真和实验结果，证明了该控制方案的可行性．

This paper presents a new vector control strategy for induction Motors without Speed Sensor. The rotor velocity is identified by sensing two phase currents and by calculating stator voltages. Simulation and imitate test arc carried out and the results shown that the control strategy is feasible.
