ABSTRACT:
A motor torque and flux controller usable with a battery-powered vehicle drive regulates the flux in the drive motor so that a constant fraction of available battery voltage is used throughout the constant-power operating range. The controller is responsive to a scalar voltage reference signal and a torque demand reference signal to produce direct and quadrature components of a current demand vector as well as a signal representative of rotor slip. Feedback for the controller is provided by a scalar signal preferably representative of a fraction of the demanded motor terminal voltage. The controller limits the magnitude of the current demand vector to a predetermined maximum while providing flux dominance.
