The invention discloses an electric tractor driving motor system control method which comprises the following steps: acquiring the rotating speed omega m [n] and the output torque T [n] of a driving motor in real time, calculating the whole vehicle acceleration a [n] and the whole vehicle traction F [n] at the moment n, and calculating the servicing mass estimated value M * [n] and the running resistance estimated value F * L [n] at the moment n according to the whole vehicle acceleration a [n] and the whole vehicle traction F [n], and introducing the curb mass estimated value and the driving resistance estimated value into an open-loop transfer function G (s) of a driving motor control loop. The method has the advantages of weakening the influence caused by the change of the traction mass and the driving resistance, ensuring the consistency of acceleration characteristics and the like.

    本发明公开了一种电动牵引车驱动电机系统控制方法,实时采集驱动电机转速ωm[n]和输出扭矩T[n],计算出n时刻整车加速度a[n]和整车牵引力F[n],根据整车加速度a[n]和整车牵引力F[n]计算得出n时刻整备质量估算值M*[n]和行驶阻力估算值F*L[n],将整备质量估算值和行驶阻力估算值引入驱动电机控制回路的开环传递函数G(s)中,本发明具有能够削弱牵引质量和行驶阻力变化带来的影响、保证加速特性一致性等优点。
