Abstract
The evaluation at low speeds of a method for torque ripple minimisation of a switched reluctance motor by the injection of a series of current harmonics is described. Adjustment of magnitude and phase of an injected harmonic is shown to lead to a corresponding minimum of torque ripple. Sequential minimisation of the lowest five harmonics removes most of the ripple, and three iterations overcomes harmonic interactions and leads close to the global minimum. Experimental results are also given
