Patent ID: 8294413

Claim:
A control system for an inverter assembly associated with an induction motor, the system comprising: a current determination module configured to generate q- and d-axis current commands based on a torque command, wherein the current determination module is further configured to generate the q-axis current command based on an observed flux linkage and a flux linkage command; a motor current control module coupled to the current determination module and configured to generate q- and d-axis voltage commands based on the q- and d-axis current commands generated by the current determination module; and a PWM modulator coupled to the motor current control module configured to generate duty cycle signals for operating the inverter assembly based on the q- and d-axis voltage commands generated by the motor current control module, wherein the current determination module configured to generate the q-axis current command based on a ratio of the flux linkage command and the observed flux linkage such that transient torque response of the motor is reduced.
