This paper proposes an approach to sensor-less predictive current control (PCC) for Permanent Magnet Synchronous Motors (PMSM) utilizing duty modulation techniques. Traditional predictive control methods often rely on additional hardware for speed sensing, leading to increased costs and computational burden. The traditional methods also produced high torque and flux ripples that led to reduced efficiency of the drive. In contrast, the proposed sensor-less model reference adaptive system (MRAS) control leverages the inherent properties of the PMSM drive system, reducing the dependency on external sensors while maintaining high accuracy and efficiency. Furthermore, utilizing duty cycle calculations, the active voltage vector is only picked for a limited time, reducing torque and flux ripples. The new method is compared to the conventional way using MATLAB/SIMULINK results to demonstrate its efficacy. The proposed method is validated using various drive cycles ensure its suitability for use in electric vehicles.
