线性ADRC在基于MRAS的PMSM无位置控制器中的运用

he application of LADRC in the sensorless control system for PMSM based on MRAS

中文摘要英文摘要

在永磁同步电机的无位置控制系统中,模型参考自适应是比较成熟的控制方案,在传统控制策略中,模型参考自适应进行转速的估计。但是在估计转速的过程中,外界的扰动比较大,同时由于传统PID在对电机控制中,存在不足。本文提出自抗扰技术(ADRC)运用于速度环中,对速度环进行优化。目前在工程中运用比较广泛的是线性ADRC,线性ADRC的参数整定相对比较简单,将自抗扰技术应用于MRAS的整个速度环控制是对传统PI控制的优化,仿真结果证明,线性ADRC相对于传PI控制,在速度环的控制上,有一定的优化和改进。

In the sensorless control system of PMSM, the model reference adaptive control is a mature control scheme. In the traditional control strategy, the model reference adaptive performs the estimation of the rotational speed. However, in the process of estimating the rotational speed, the disturbance is relatively large, and at the same time, the conventional PID is insufficient in controlling the motor. This paper proposes that ADRC is used in the speed loop to optimize the speed loop. Currently widely used in engineering is the linear ADRC, the parameter setting of the linear ADRC is relatively simple, the application of the ADRC technique to the entire speed loop control of the MRAS is the optimization of the traditional PI control, and the simulation results prove that the linear ADRC is relatively The traditional PI control has certain optimization and improvement in the control of the speed loop.
