| Abstract: | Some approach to estimate induction motor speed from measured terminal voltages and currents for speed-sensorless control are proposed.The proposed approach are based on observing the counter electromotive force vector or the instantaneous reactive power of the rotor flux.And then a hardware architecture and software figure are put forward.The simulation results and some theoretical problems for its practical application are discussed. |
| Keywords: | induction motor vector control speed-sensorless control instantaneous reactive power theory |
