电传动装甲车辆轮毂电机宽速域矢量控制

Research on Wide Speed Range Vector Control of Hub Motor for Electric Drive Armored Vehicles

为使装甲车辆在运行过程中获得良好工作状态,通过在基速以下区域采用基于滑模极值搜索(Sliding Mode Extreme value Search Control,SMESC)的最大转矩电流比(Maximum Torque Per Ampere,MTPA)控制算法(SMESC-MTPA)和在基速以上区域使用弱磁控制算法的方式控制电传动装甲车辆轮毂电机,并考虑电流在高速段的交叉耦合效应及电机参数变化影响,在基速以上区域使用变交轴的单电流控制法进行弱磁控制,进而搭建基于MATLAB/Simulink的仿真模型,并通过仿真验证了该控制策略的正确性。

In order to make the armored vehicle work well during operation,the control algorithm of Maximum Torque Per Ampere(MTPA)based on Sliding Mode Extreme value Search Control(SMESC)is adopted to controll the hub motor of electric drive armored vehicle in the area below the base speed,and the flux-weakening control algorithm is used in areas above the base speed.Considering the cross coupling effect of the current in the high speed section and the influence of motor parameter changes,the single current control method with variable quadrature axis voltage is used for flux-weakening control in areas above the base speed.On this basis,a simulation model based on MATLAB/Simulink is built,and the correctness of the proposed control strategy is verified through simulation.
