| Abstract |
Field oriented sensorless speed control of induction motors can become unstable at low frequency. A possible method to prevent unstable operation is to change the open loop control at low speed. This paper presents a field oriented sensorless speed control in combination with a new method of open loop control with better dynamic behavior. Furthermore an identification method of the electrical parameters at standstill is presented. |
