Abstract:

Part 3 of 3 of the Second Annual Report covers control activities performed unde Task c - Design of the SRM Converter of this ONR Grant. The activities were performed from 5199 to 53000. This report, first, derives a set of nonlinear equations to characterize the inherent relationship among phase voltage, phase current, rotor position and instantaneous phase torque. Then, the report proposes a control scheme for torque ripple minimization based on a torque controller. Next, it describes a fuzzy logic controller to adjust the turn-on and turn-off angles. Finally, simulation results are evaluated at different rotor speeds to illustrate the feasibility of the proposed ideas.
