Abstract
Optimal operating criteria of SRM involve maximizing the average output torque with minimum torque ripple through the excitation of different stator phases with appropriate excitation and commutation angles. This paper presents a micro-genetic algorithm (μGA)-based optimization for firing and commutation angle estimation for an SRM drive. A 1 + [n/2 Random] bit mutation is proposed in the μGA process to accomplish global maxima in the optimization. The mathematical model of SRM drive system has been developed to validate the optimization results. The credibility of the approach has been verified by implementing a mono-objective optimization to find the optimal excitation and commutation angles by maximizing the average output torque per phase. Results are compared with the existing approaches for the same operating conditions and are also verified for a couple of operating conditions using the MATLAB simulation and the results are presented.
