基于模糊PI模型參考自適應(yīng)的高速永磁同步電機(jī)轉(zhuǎn)子位置檢測(cè)
[Abstract]:Aiming at the characteristics of high speed permanent magnet synchronous motor (PMSM) with high speed and wide speed range, a fuzzy PI model reference adaptive (model reference adaptive system,MRAS (model reference adaptive system,MRAS) observer is proposed to detect the rotor position of PMSM. In this method, the fuzzy PI regulator is applied to the model reference adaptive observer, and the proportional integral coefficient of the PI regulator is adjusted by the fuzzy controller, so that the PI regulator can have good dynamic and steady performance in a wide range of motor speeds. The model reference adaptive observer is used to detect the rotor position of high speed permanent magnet synchronous motor (PMSM). Finally, the Matlab simulation and experiment of 4 kW high speed permanent magnet synchronous motor with fan load are carried out, and the rotor position detection and velocity estimation based on this method are realized. The source of rotor position error and the compensation method are analyzed. It is proved that the proposed method is suitable for rotor position detection of high speed permanent magnet synchronous motor (PMSM).
