Adaptive Energy-Efficient and Resilient Control of a PMSM Drive for Electricity 5.0 Applications

This study proposes an Electricity 5.0-oriented supervisory control framework for an interior permanent-magnet synchronous motor (IPMSM) drive that integrates field-oriented control, MTPA, field weakening, loss-minimization control (LMC), speed estimation, and adaptive mode selection. Four operating modes, Performance, Balanced, Eco-LMC, and Resilient, are coordinated according to dynamic, electrical, and sensing conditions. The framework is evaluated under variable-speed operation, load disturbances, motor-parameter variations, DC-link voltage reduction, sensor degradation, and combined disturbances. Performance Mode achieves the lowest speed RMSE of 44.52 rpm, while Eco-LMC reduces iron-loss energy by 26.6% and total modeled electrical losses by 10.2%, with a 2.1% reduction in consumed electrical energy. During sensor degradation, the speed observer maintains an RMSE of approximately 19–21 rpm. In the combined supervisory scenario, only eight mode transitions occur, confirming effective chattering suppression through hysteresis and a 35 ms dwell time. No sustained SVPWM saturation is observed in any scenario. The results demonstrate that adaptive coordination of performance, efficiency, and resilience can improve PMSM drive operation within an Electricity 5.0-oriented control framework.
