摘要：
The flux leakage controllable permanent magnet (FLC-PM) motor can provide wide speed regulation and high output torque due to its unique magnetic flux leakage design. As a result, it can meet the requirements for high efficiency in various operating conditions for electric vehicles. However, due to the motor’s specialized flux leakage magnetic circuit design, its sensorless control drive system can experience periodic and nonperiodic harmonic disturbances, as well as loop delay issues, which can significantly impact the estimated performance of the rotor position. To address these challenges, this paper proposes a novel sensorless control method that uses an adaptive disturbance compensation observer. The first step in this approach is to implement an adaptive disturbance iterative learning control method. This technique enables suppression of periodic and nonperiodic disturbance harmonics and reduction of harmonic content in the current. Next, an adaptive compensation position observer is designed to observe and compensate for estimated position errors online, which improves the estimated accuracy and dynamic performance of the FLC-PM motor drive system. Finally, experiments were conducted to validate the feasibility and effectiveness of this control method. © 2024 Chinese Academy of Sciences. All rights reserved.
