A Unified Approach for Four-Quadrant Optimal Controlled Switched Reluctance Machine Drives With Smooth Transition Between Control Operations

摘要

The aim of this paper is to unify the optimal control of a switched reluctance machine in a four-quadrant drive with smooth transition between the control-mode operations. The smooth transition is attained since the firing angle conditions of one operating mode are derived from the conditions of the other operating mode. The proposed control scheme is easily implemented since the knowledge of the machine magnetization curves is not required. Experimental results on a prototype control system are presented to validate the theoretical considerations and demonstrate the effectiveness of the proposed control scheme.
