Abstract
An induction motor control system (10) for electric vehicles having a DC power supply (14), an inverter (16), an induction motor (12), a motor controller (26) and a vehicle-level controller (32). The method and system of the present invention optimizes the torque output for the induction motor and utilizes minimum power. The method and system of the present invention calculates the flux current such that the slip frequency is maintained at a nominal level, thereby producing peak torque.
