Abstract
In one embodiment, the method includes i) obtaining target data specifying desired operating parameters of a switched reluctance motor, ii) obtaining data indicative of a value of a measured drive current for each of the phase outputs of an associated inverter, iii) converting the measured drive current values from a stationary reference frame into reference current values in a rotating reference frame, iv) generating, based on the reference current values and the target data and the set of inductance values, updated reference voltage values in the rotating reference frame, v) converting the updated reference voltage values from the rotating reference frame into updated voltage values in the stationary reference frame, and vi) controlling the inverter to set the voltages of the phase outputs to the updated voltage values.
