A scalar control supplemented by a decoupler transfer function control is provided to develop frequency and current commands for a current controlled inverter driving an induction machine. The machine torque is controlled by the slip and corresponding torque producing component of stator current. The rotor flux is maintained constant by the flux component of stator current. The total stator current is controlled to hold rotor flux constant with desired torque during steady state conditions and the decoupler compensator varies stator current to maintain rotor flux constant during transient conditions.
