| Abstract: | A new and simple method for estimating the rotor speed is developed. The slip frequency estimation is of great importance for the control system without a speed sensor. The system performance analyses are made for a direct field oriented vector control system, an indirect field oriented vector control system and a direct torque control system, respectively. It has been proved that keeping a constant amplitude of flux is an important factor for system performance. |
