摘要:
针对纯电动汽车两挡双离合自动变速器(two-speed dual-clutch transmission, 2DCT)换挡控制模型及参数的不确定性和存在的未知干扰,提出了一种线性自抗扰(linear active disturbance rejection controller, LADRC)换挡控制策略。首先建立2DCT换挡过程动力学模型,并分析了换挡过程;然后考虑控制模型的不确定性及未知干扰,将LADRC控制器应用到换挡过程对期望角速度进行跟踪,并采用扩张状态观测器(extended state observer, ESO)对扰动进行实时估计,并加以补偿,最后与PID控制进行对比。仿真和实验结果表明,该控制器跟踪误差更小,鲁棒性强,能保证良好的换挡品质。
