摘要

永磁同步电机（Permanent Magnet Synchronous Motor，PMSM）弱磁控制系统常用于电动汽车领域。电动汽车运行于低速时，PMSM需要输出大转矩，以响应快速起步、加速及爬坡需求；电动汽车运行于高速，且超过额定速度时，PMSM处于弱磁状态，需具备一定的带载能力，以满足高速行驶和超车工况。针对PMSM弱磁控制中的转速突变，文章设计了自抗扰控制器（Active Disturbances Rejection Controller，ADRC）替代速度外环PI控制器，对扰动项快速观测和补偿，减小速度突变对系统造成干扰，实现转速精准跟踪。针对转矩项干扰，结合转矩和磁链输出值设计有限集模型预测控制（Finite Control Set Model Predictive Control，FCS-MPC）以替代传统直接转矩控制（Direct Torque Control，DTC），构建令转矩和磁链脉动最小的价值函数，再通过价值函数的计算寻优，选取出最优空间矢量控制信号输送给逆变器。基于ADRC和FCS-MPC的优化作用，弱磁控制系统的抗扰能力、电流和转矩输出精度增强，试验验证了所设计系统的可行性和性能优势。

Abstract

The field weakening control system for permanent magnet synchronous motors (PMSM) is commonly used in the field of electric vehicles (EV). PMSMs need to deliver high torque output to meet the demands of rapid starting

acceleration

and climbing for EVs when operating at low speeds. Moreover

they needs to maintain a certain load capacity in a field weakening state to support high-speed driving and overtaking for EVs when operating beyond the rated speed. To address speed mutations in PMSM field weakening control

this paper proposes the design of an active disturbance rejection controller (ADRC) to replace the proportional integral (PI) controller in the speed outer loop. The ADRC can quickly observe and compensate for disturbance terms

reducing system interference caused by speed mutations and enabling accurate speed tracking. To mitigate torque term interferences

this paper presents a combination of finite control set model predictive control (FCS-MPC) and a model predictive torque control system based on torque and flux linkage output design

to replace traditional direct torque control (DTC). Based on a value function constructed to minimize torque and flux linkage ripples

calculations and optimizations enable the selection of optimal space vector control signals that are then transmitted to the inverters. The optimized field weakening control system

incorporating both ADRC and FCS-MPC

demonstrates improvements in disturbance immunity

as well as current and torque output torque. The feasibility and performance advantages of the designed system are verified through experiments.
