Implementation of a DSP-based grey integral variable structure controller for synchronous reluctance motor drive

A DSP-based grey integral variable structure controller for a synchronous reluctance motor is presented. The mathematical model for the synchronous reluctance motor includes core loss. We develop a maximum torque strategy to improve the low torque performance. The grey integral variable structure controller is used to reject the parameter variations and uncertain bounded external disturbances. The grey predictor can predict the future state development. The proposed scheme is demonstrated through experiments using dSPACE DS1102 controller board, which includes the processor of TMS320C31 and TMS320P14. Simulation and experimental results show that the proposed controller is valid for the synchronous reluctance motor.
