摘　　要：基于对模型参考自适应(MRAS)算法估计永磁同步电机(PMSM)转速和位置原理的分析,针对传统的pi自适应律,提出了一种基于模糊自适应律的模型参考自适应复合控制算法。建立了永磁同步电机无速度传感器和带速度传感器的矢量控制仿真模型并进行分析,仿真结果表明与传统的模型参考自适应无速度传感器方法相比,改进算法后的系统具有更好的带负载能力,与带速度传感器控制系统相比也具有较好的控制性能。Based on the analysis of the principle of using MRAS algorithm to estimate the speed and position of permanent magnet synchronous motor,for the traditional pi adaptive law,this paper presents a composite control algorithm based on fuzzy adaptive law.Establish permanent magnet synchronous motor which has speed sensor and sensorless vector control simulation model.The simulation results show that compared with the traditional MRAS algorithm control system has better load capacity and compared with the sensor control system,the proposed algorithm also could obtain relatively good results.
