摘　　要：针对电励磁同步电机(EESM)在车用电机控制方向的研究,通过Maxwell设计EESM有限元模型,基于Simulink搭建电机控制系统模型。然后,根据凸极EESM的电机特性和电磁转矩分析,在控制系统中采用最大转矩电流比(MTPA)矢量控制方式在Simulink-Maxwell进行EESM控制系统的联合仿真验证。同时,控制系统电流环应用线性自抗扰控制(LADRC),基于电机已知参数在LADRC中设计模型辅助—扩张状态观测器(MA-LESO),以观测和消除系统扰动变量。仿真实验表明,采用MTPA矢量控制的电机在带载时转速波动降低,带载能力增强;在电流环中采用MA-LESO的LADRC控制器能使电机转速在稳态时波动更小,在带载时的抗干扰性能更强,电机运行过程相对稳定;电机负载转矩和定子电流在空载、负载时的波形更稳定,显著提升了电机运行性能。Regarding the research on electric excitation synchronous motor(EESM)in the field of vehicle motor control,a finite element mod-el of EESM was designed using Maxwell,and a motor control system model was built based on Simulink.Then,based on the motor characteris-tics and electromagnetic torque analysis of the salient pole EESM,the maximum torque to current ratio(MTPA)vector control method was ad-opted in the control system to conduct joint simulation verification of the EESM control system in Simulink Maxwell.At the same time,the cur-rent loop of the control system applies linear active disturbance rejection control(LADRC),and a model auxiliary extended state observer(MA-LESO)is designed in LADRC based on known motor parameters to observe and eliminate system disturbance variables.Simulation ex-periments show that the motor using MTPA vector control reduces speed fluctuations and enhances load capacity when loaded;The use of MA-LESO's LADRC controller in the current loop can reduce the fluctuation of motor speed in steady state,enhance anti-interference performance under load,and ensure relatively stable motor operation;The waveform of motor load torque and stator current is more stable under no-load and load conditions,significantly improving the operational performance of the motor.
