Magnetic saturation effects on the control of a synchronous reluctance machine

Abstract

Experimental results of the magnetic saturation effects on the control of a small reluctance synchronous machine (600 W) are presented in this paper. The modeling of the machine without saturation effects is first developed using the space vector theory and then, the electrical parameters measurement are given. A rotor-oriented vector control of the synchronous reluctance machine is achieved with a DSP board (TMS320C31) and experimental results are presented. When the magnetic circuit is unsaturated, the simulation shows a good accuracy of the results when they are compared to the experimental ones. Change differences appear with the saturation.
