Patent ID: 8773056

Claim:
A control system for a switched reluctance (SR) machine having a rotor and a stator, the control system comprising: a converter circuit operatively coupled to the stator and including a plurality of gates in selective communication with each phase of the stator; and a controller in communication with each of the stator and the converter circuit and configured to execute two or more processes in parallel, the processes including: generating a torque command based on one or more of bus voltage, machine current, rotor speed and rotor position, determining a first set of current control parameters based on the torque command and the rotor speed, determining a second set of current control parameters based on one or more of the torque command, the rotor speed and the rotor position, selecting one of the first and second sets of current control parameters based on the rotor speed, and operating the gates according to the selected set of current control parameters.
