摘要
传统的直线加减速和指数加减速算法在运动过程中的柔性冲击比较大,不能满足如LED粘片机这类设备高速、高效、高精度的要求。针对这种情况,提出了五次多项式拟合的新型S曲线加减速算法,结合LED粘片机的实际应用,给出了位移、速度、加速度及加加速度的函数表达式,并在归一化的基础上,给出了估算最大值的准确表达式,为LED粘片机的加减速控制及电机的合理选型提供了更可靠的参考。
The traditional acceleration/deceleration algorithm based on liner method and exponential method is not suitable for equipments of high - speed ＆ high - precision, such as LED die - bonder because of the vibration caused by acceleration discontinuity affects. In order to solve this problem, it puts forward a new control method of fifthdegree polynomial acceleration/deceleration algorithm. Aiming at the LED die -bonder, it shows the function of displacement, speed, acceleration and jerk, introduces also the normalization form of the functions including the expression of maximum value of the functions. This algorithm supplies a reliable reference for acceleration/deceleration controlling and motor selection.
