Enhanced Robust Deadbeat Predictive Current Control for Induction Motors

Deadbeat predictive current control (DPCC) uses many machine parameters when calculating the reference stator voltage vector. The performance of DPCC may severely deteriorate if the motor parameters used in the controller are not accurate. To improve the parameter robustness of DPCC, this paper proposes a robust DPCC (RDPCC), which utilizes the error between the measured currents and predicted currents to compensate for the influence of machine parameter mismatches. The proposed method is compared with the DPCC, and the experimental results confirm its strong robustness against motor parameter variations.
