基于联合仿真的电励磁同步电机线性自抗扰控制
Linear Active Disturbance Rejection Control of Electric Excitation Synchronous Motor Based on Co-Simulation
摘要
Abstract
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.关键词
