【摘要】：针对高速永磁同步电机转速高、调速范围宽的特点,该文提出了一种模糊PI模型参考自适应(model reference adaptive system,MRAS)观测器,实现了永磁同步电机转子位置检测。此方法将模糊PI调节器应用于模型参考自适应观测器,通过模糊控制器调整PI调节器的比例积分系数,以使PI调节器能在电机很宽的速度范围内都具有良好的动稳态性能,提高了模型参考自适应观测器对高速永磁同步电机转子位置的检测精度。最后,以带有风机负载的4 kW磁悬浮轴承高速永磁同步电机为研究对象进行了Matlab仿真和实验,实现了基于此方法的转子位置检测和速度估计,并分析了转子位置误差产生的来源以及补偿方式,证明所提方法适用于高速永磁同步电机的转子位置检测。
[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).
