Abstract

Axial-Flux Self-Bearing Motors (AFBMs) are distinguished by considerable variations in inductance resulting from axial displacement. Conventional controllers are frequently engineered to accommodate a wide range of inductance changes. Nevertheless, this methodology is often suboptimal, particularly when inductance is not accurately determined. This paper puts forward a novel inductance approximation function for the stator, designed to minimize modeling errors. Furthermore, an advanced control strategy is presented, based on a sliding mode controller with online adaptive parameter tuning. The experimental results demonstrate the efficacy of the proposed control strategy, exhibiting enhanced performance, stability, and robustness across a range of operating conditions.
