Switched reluctance motor power estimation compensation for variable DC-link voltage
A control system (200) for a switched reluctance (SR) motor (206) includes a Direct Current (DC) power source (202), and an inverter (204). The control system (200) includes a user interface configured to enable an operator to specify a desired torque output. The control system (200) further includes a controller (216) which converts a DC current from the Alternating Current (AC) supplied to the SR motor (206) by the inverter (204). The controller (216) estimates an actual power output generated by the SR motor (206) based on a DC voltage supplied by the DC power source (202) to the inverter (204), and the converted DC current. The controller (216) estimates an actual torque output based on the actual power output and a rotational speed of the SR motor (206). The controller (216) compares the actual torque output and a desired torque output to calculate a torque error. The controller (216) adjusts a torque output limit and the rotational speed of the SR motor (206).
