FPDA closed loop electric drives controls

A current controller for an electric drive of a switched reluctance (SR) machine having a rotor and a stator, the current controller comprising:

• a torque control module configured to generate a torque command based on one or more of bus voltage, machine current, rotor speed and rotor position;
• an average torque control module configured to determine a first set of current control parameters based on the torque command and the rotor speed;
• a current profiling module configured to determine a second set of current control parameters based on one or more of the torque command, the rotor speed and the rotor position;
• a control select module configured to select one of the first and second sets of current control parameters based on the rotor speed;
• and
• a current control module configured to selectively drive a plurality of gates associated with each phase of the stator according to the selected set of current parameters.
