Abstract

This paper deals with modeling and control of a three-phase permanent magnet synchronous machine (PMSM) with sinusoidal back electromotive forces (emf) under supply fault conditions. The overall system is modeled thanks to the energetic macroscopic representation (EMR) formalism considering that a fusible element opens the phase circuit. Using systematic inversion rules of the EMR, a maximum control structure (MCS) is deduced. Based on the analysis of degrees of freedom (DOF) of the drive, two control strategies for constant-torque under supply fault conditions are inferred. One method balances generated perturbations caused by the supply fault and the other one consists in modifying current controller´s structure. These methods are validated through simulations with Matlab software
