一种新型的电梯门机S型控制曲线的构建方式

An Innovitive Method of S-curve Generation for Elevator Door Servo

在门机应用中,为了避免门机系统在运行时发生机械碰撞,并提高整体运行舒适度,提出了S曲线拐点实时计算法,根据对运行距离的准确估算,实时计算曲线拐点,拟合曲线。针对新方法,本文对传统曲线进行了离散化处理,详细推导了曲线距离计算公式和软件流程图。实验结果表明,构建曲线平滑完整,距离控制准确,能自动适应各种门宽系统。

In door machine applications, in order to avoid the collision in the system running, improve the o- verall running comfort, bring forward the S curve-break real-time calculation method, based on the accurate estimation of ruing distance, calculate the real-time curve-break, generate curve. For new method, the arti- cle made a discrete transform of the traditional curve, derived the curve distance calculating formula and soft- ware flow chart in detail. Experiment results show that smoothie of the curve generated, accuracy of the dis- tance control can adjust any door-width system automatically.
