N2 - Permanent magnet assisted synchronous reluctance motors (PMa-SynRMs) are favored for their merits of high efficiency and low costs. Removed position sensor may bring lower costs and higher reliability. However, flux-based sensorless methods have drawbacks of system latency and complextity. This paper presents an adaptive nonlinear flux observer (ANFO) for high-precision sensorless control of PMaSynRMs. The ANFO leverages active flux error feedback compensation with gain parameters dynamically adjusted via rotor speed and stator current magnitude, eliminating the need for high-pass filters or complex parameter identification. Finally, experiments on a 2.2 kW PMa-SynRM platform validates the effectiveness of the proposed method.
