摘要
调速永磁同步电动机以其体积小、效率高、过载能力强、功率密度高等特点适合应用于电动汽车的驱动系统.本文在电动汽车中采用的调速永磁同步电动机是基于模糊自抗扰控制的直接转矩控制策略,在直接转矩控制系统中引入自抗扰控制器,可有效提高系统的动态性能控制品质;应用模糊控制实现待整定自抗扰控制参数的在线自整定,提高控制系统的自适应能力.构建了在MATLAB/Simulink环境下的仿真结构图,仿真结果表明,电动汽车用调速永磁同步电动机的模糊自抗扰直接转矩控制与传统的直接转矩控制相比,提高了系统的响应速度并减小了转速超调量,降低了调速过程中的磁链和转矩脉动,从而提高了电动汽车行驶的平稳性.
The variable speed permanent magnet synchronous motor is suitable for the driving system of electric vehicles because of its small size,high efficiency,strong overload capability and high power density.A direct torque control(DTC)strategy of SRPMSM for electric vehicle based on fuzzy active disturbance rejection control(ADRC)was proposed.The ADRC was introduced into direct torque control system to improve the dynamic performance control quality of the system.The fuzzy control is used to realize the online self-tuning of the self-disturbance control parameters to be adjusted,and the adaptive ability of the control system is improved.The simulation structure diagram was constructed in MATLAB/Simulink.The simulation results showed that compared with the traditional DTC,the DTC of SRPMSM based on fuzzy ADRC for electric vehicles can improve the response speed of the system,this way can reduce the flux and torque ripple in the process of speed regulation,so as to improve the smoothness of electric vehicle driving.
