Abstract A control for an inverter-driven switched reluctance generator includes an angle control for generating a turn-on angle signal and a pulse width angle signal for switching respective inverter switches according to a function F(θ on , θ off ) which depends on the machine geometry and speed of operation. A linearizer is provided for adjusting the turn-on angle signal and the pulse width angle signal by varying the value of the function F(θ on , θ off ) inversely with the dc bus voltage so as to maintain a substantially constant average generator current. In this way, open loop operation of the switched reluctance generator drive is stabilized, and closed loop operation is improved, i.e., by making the system response to step load and commanded voltage changes independent of the dc bus voltage. The control further includes a commutator for switching each respective phase of the switched reluctance generator drive according to the adjusted turn-on angle signal and the adjusted pulse width angle signal generated by the linearizer.
