Vector Control of a Variable Reluctance Machine Stator and Rotor Discs Imbricates

This study was devoted, in its first part, to the configuration and the modelling of the Imbricate Discs Variable Reluctance Machine (IDVRM), which was simplified with the assumption of stator structure alike to that of the synchronous machine, leading to the possibility of using the PARK's transformation. Then, a vector control strategy, which maintains a constant saturation level in the machine, was set-up. This strategy, which consists in keeping the stator direct current at a constant value, allowed the linearization of the machine model and the control was chose in the same way as a DC machine. A simulation by Matlab/Simulink of the IDVRM, fed by PWM inverter, showed the simplicity and the effectiveness of the proposed control strategy for this type of machine.
