Abstract :
Optimal precalculation of the position-phase current profile for current feeding a four-phase, 4 kW switched reluctance motor results in a single-input, linear, decoupled output torque controller that provides low torque ripple. A bicubic spline interpolation was used to model the nonlinear experimental data. The algorithm is based on minimizing both the average and peak current and hence improves the dynamic performance of the novel six-switch, current-fed, 4 kW, 40 kHz IGBT inverter. Test results are presented
