Switched reluctance motor power estimation compensation for variable DC-link voltage
A control system for a switched reluctance (SR) motor includes a Direct Current (DC) power source, and an inverter. The control system includes a user interface configured to enable an operator to specify a desired torque output. The control system further includes a controller which converts a DC current from the Alternating Current (AC) supplied to the SR motor by the inverter. The controller estimates an actual power output generated by the SR motor based on a DC voltage supplied by the DC power source to the inverter, and the converted DC current. The controller estimates an actual torque output based on the actual power output and a rotational speed of the SR motor. The controller compares the actual torque output and a desired torque output to calculate a torque error. The controller adjusts a torque output limit and the rotational speed of the SR motor.
