| 摘 要： | 在YL-335B自动化生产线实训考核设备的分拣单元中,驱动传送带的三相异步电机在制动后的滑行距离受变频器设定的运行频率和下降时间影响,存在不确定性,导致工件不能准确地停在预定位置。通过采集大量滑行距离数据,采用多项式曲线拟合的方法,构建了滑行距离与运行频率和下降时间的数学模型,并提出提高三相异步电机定位精度的自适应控制方法。实验结果表明,该控制方法可根据运行频率和下降时间,自适应控制电机的停机位置,工件定位准确。

| Abstract: | The uncertainty exists in the sorting unit of YL-335 B automatic production line training and assessment equipment and in the effect on the sliding distance of three-phase asynchronous motor driving conveyor belt after braking by the frequency and time of frequency converter setting, which leads to the inaccurate stop of workpiece in pre-positioning. By collecting a large amount of gliding distance data and using polynomial curve fitting method, a mathematical model of gliding distance, running frequency and falling time is constructed, and an adaptive control method to improve the positioning accuracy of three-phase asynchronous motor is proposed. The experimental results show that the control method can self-adaptively control the stop position of the motor and locate the workpiece accurately according to the running frequency and falling time. |
