A new fault diagnostic parameter, applied to switched reluctance motor drives, is presented. The proposed parameter is a partial average power based on the power converter supply current and the rotor mechanical position information. At high speed operating conditions phase current is not regulated and the machine closed-loop control only needs to observe one current, which is the power converter...
A fault tolerant control strategy of SRM drives is presented. The mean rotor mechanical speed is sustained, under the absence of one motor phase, due to an increase in the electromagnetic torque reference and the consequent increase of the healthy phases current amplitudes. Dynamic problems as excessive pick phase current and electromagnetic torque overshoot, due to the lack of one motor phase, are...
