    PID Gains-Based Super-Twisting control of a Synchronous Reluctance Machine
    (BOUNADJA Elhad, 2025) BOUKECIAT, Bouchra; HIRECHE, Sabrina
    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
