High Efficiency and Quick Response of Torque Control for a Multi-Phase Machine Using Discrete/Continuous Approach: Application to Five-phase Permanent Magnet Synchronous Machine

摘要

This article presents a hybrid control strategy (Discrete/Continuous) for controlling the five-phase permanent magnet synchronous machine powered by a voltage inverter. The hybrid aspect of this approach comes from the fact of taking into account the voltage inverter and the machine in a unified manner during the modelling process, i.e. modelling includes at the same time continuous and discrete variables. Simulation results performed under Matlab/Simulink are presented and discussed for the purpose of the performances verification of the proposed control strategy. The obtained results will show in particular the principal advantages of the adopted control strategy like the enhancement of the dynamic torque response of this machine, and the oscillations' minimization of controlled parameters such as torque and current.
