Résumé:
The Synchronous Reluctance Motor (SynRM) is a robust and efficient AC machine
that generates torque through the variation of magnetic reluctance, without the need for rotor
windings or permanent magnets. This Master’s thesis investigates the modeling and advanced
control of SynRMs to improve their dynamic performance and robustness. A detailed analysis of
the motor's structure and its d-q frame model reveals strong flux–torque coupling, which
complicates control and necessitates decoupling strategies. A rotor flux-oriented vector control
approach is first implemented, yielding satisfactory results under nominal conditions but
showing performance degradation under parameter variations. To address these limitations, a
PID-based Super-Twisting Sliding Mode Controller (PID-STC) is proposed. This controller
integrates robustness, fast dynamic response, and reduced chattering. Simulation results confirm
its superiority over conventional PI and classical STC controllers in terms of precision and
disturbance rejection
