摘要
研究了一种基于矢量控制的模型参考自适应永磁同步电机无速度传感器方案。该方案仅利用q轴的估算电流与实际电流之差作为误差信号,将误差信号送入PI调节器进行调节后得到估计转速。本文对该方案进行了仿真和实验比较,结果表明本文提出的方案在高低速均能准确检测到转子的位置和速度,具有良好的动静态运行性能。
In this paper, a amended method of estimating the rotor speed about model reference adaptive system （MRAS） on the basis of vetor control is put forward. It only needs the error signal between q axis estimated current and q axis actual current. Then estimated speed is gained by using PI regulator which adjusted error signal. Comparative study of simulation and experiment between this novel sensorless scheme and the scheme in reference literature are presented in this paper. The results show that this novel method is capable of precise estimating the rotor position and speed under the condition of high or low speed. It also possesses good performance of static and dynamic.
