Abstract
This paper manages synthetically non-linear calculation, FEM and magnetic circuit method designing prototype SRM and realizing an approach of control strategy. SRM designing uses FEM revising technique. Novel speed control scheme based on the torque ripple minimization for a 12/8 SRM control system is proposed. This proposed strategy is that outer loop is a PI speed controller; inner loop is fuzzy logic direct drive control (DDC) with current chopping control for SRD at low speed and PI current control at high speed. An intelligent controller based on the scheme is completed. In frame of fuzzy logic at low speed controlling strategy, the inductance data is only set. Experiment results show the feasibility of the proposed strategy.
