Abstract
This paper addresses a basic control issue in switched reluctance
motor (SRM) drives-the production of a ripple-free torque. Simple and
largely model-independent conventional supply waveforms are not able to
satisfy this requirement. The goal of this paper is to improve SRM
dynamical performance by compensating for motor nonlinearities, while
maintaining the robustness of conventional methods. The method is based
on a complete parameterization of position-dependent voltage and current
profiles in ripple-free operation, and on a waveform optimization to
minimize power supply requirements. Furthermore, model uncertainties are
included to show that the proposed strategy consistently outperforms the
conventional policy. Experimental data verifying the analytical approach
are included
