摘要

本文的目标是在较宽的转速范围内，以最少的时间和较低的成本控制永磁同步电动机的速度。因此，本文对基于调速的永磁同步电机进行了性能对比分析。对无传感器的场定向控制(FOC)和无传感器的模型参考自适应系统(MRAS)进行了比较。利用估计的转速偏差作为PI控制器的反馈信号，实现了永磁同步电机的无传感器转速控制。在MATLAB Simulink软件中对两种控制策略的性能进行了评估。仿真研究显示了永磁同步电机在不同负载和转速变化条件下的转速响应。结果表明，与未采用MRAS控制系统的系统相比，MRAS技术可以有效地估计转子转速，精度高，转矩响应速度快。

Performance analysis of PMSM drive based on FOC technique with and without MRAS method

The objective of this paper is to control the speed of Permanent Magnet Synchronous Motor (PMSM) over wide range of speed by consuming minimum time and low cost. Therefore, comparative performance analysis of PMSM on basis of speed regulation has been done in this study. Comparison of two control strategies i.e. Field oriented control (FOC) without sensor less Model Reference Adaptive System (MRAS) and FOC with sensor less MRAS has been carried out. Sensor less speed control of PMSM is achieved by using estimated speed deviation as feedback signal for the PI controller. Performance of the both control strategies has been evaluated in in MATLAB Simulink software. Simulation studies show the response of PMSM speed during various conditions of load and speed variations. Obtained results reveal that the proposed MRAS technique can effectively estimate the speed of rotor with high exactness and torque response is significantly quick as compared to the system without MRAS control system.
