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,...
The results demonstrate high soil twin synchronization accuracy, with an overall RMSE of 1.47 percentage points and R2 of 0.981, based on experimental field measurements, demonstrating the potential of the proposed digital twin framework for integrated water–energy management in smart agriculture.
