一种活动发射平台弯道行走主动差速自动控制方法

An Active Automatic Speed Control Method in Different Speeds on Crooked Railway of Drive Control System of Mobile Launch Platform

为确保某运载型号活动发射平台在包含直线轨道与圆弧形轨道的复杂轨道上完成运载火箭的垂直转运任务,为其驱动控制系统设计了一种弯道行走主动差速自动控制的方法。该方法通过采集轮组上安装的绝对值编码器的信息,确定每一个轮组在轨道上的精确位置信息,给定变频器不同的输出频率,从而控制各轮组的主动差速实现活动发射平台在圆弧形轨道上的运行及直轨弯轨之间的变轨运行,实现了活动发射平台在复杂轨道的平稳行走,有效地提高了活动发射平台的性能。

In order to complete the vertical transport mission of rocket in complex track, including straight and winding track, an active automatic speed control method in different speeds on crooked railway of drive control system of mobile launch platform is designed. It collectes the pulse of absolute value of encoder on wheels to get the positions of every pair of wheels and controlls the speed of wheels, which achieves the movable launch platform running on complex track smoothly, improves the performance of launch platform effectively.
