The essential part of determining the initial as well as the instantaneous rotor positions are conducted by using the feedback values from the line voltages and the incremental speed encoder. The rotor speed and position obtained are then used to determine the voltage command for the close-loop control system. The overall system is composed of a speed and two current controllers, and a sinusoidal pulse-width modulated inverter. The speed controller adopts the proportional-integral control technique, while the current regulator uses the decoupled current controller and the voltage command compensator. Excellent Performance concerning speed, torque, current and efficiency through the proposed scheme. The system realized can also be operated in the constant hose-power region where field-weakening is introduced. Accurate torque control and efficiency improvement in this region are resulted by appropriately adjusting the input as well as the field currents.
