Abstract :
With the proposed dual-current-loop control algorithm, the torque and air-gap flux of a doubly fed induction motor are controlled directly. Compared to the singly fed permanent magnet and induction motors, the torque-speed operation region for electric vehicle/hybrid electric vehicle applications is nearly doubled with the proposed dual-current-loop control algorithm for a given battery voltage. Computer simulations and experimental results are provided to verify the proposed control algorithm.
