为避免人和物在电动车窗玻璃上升过程中被夹伤,研究了一种面向工程应用的电动车窗防夹控制算法。首先应用滑模估计器对电动车窗不确定的外部扰动力矩进行估计,然后根据实验确定摩擦力矩的特性,并结合频谱分析结果,探讨了将摩擦力矩从估计出的外部扰动力矩中分离出来的方法,提高了对路面干扰力矩和障碍物阻挡力矩的估计精度,进而给出了一种新的车窗防夹算法。实验结果表明,该方法可行、有效,具有计算速度快、易于实现、占用内存少等优点,便于工程应用。

To avoid injury to people and damage to articles caused by pitch of the electric mobile window during its rising ,a practical anti-pitch control algorithm is researched .Firstly ,the sliding formwork esti-mator is adopted to make estimation to the unconfirmed external disturbance moment of the electric mobile window ,and then the characteristics of the friction moment are confirmed by experiment ,and a method to separate the friction moment away from the estimated disturbance moment has been studied ,so the estima-tion of road surface disturbance moment and barrier obstruction moment becomes more accurate ,and thus a new window anti-pitch algorithm is given .The experiment results have proved that this method is feasi-ble and effective ,and it is rapid in computation ,easy to be achieved and takes little memory ,so it is adap-tive to the engineering application .
