摘要
新型石油管道纤维缠绕含胶量控制系统采用伺服电动机粗动控制与压电陶瓷精动控制相结合的方法实施含胶量的精密定位控制 ,利用衍射干涉光栅测长技术进行实时检测 ,实现了执行机构的闭环控制。系统工作行程 50mm ,定位精度± 0 1 μm。利用单片机作为控制核心 ,与胶量检测机构一起构成闭环控制系统 ,并可以与上位机实现通讯。该系统重复性好 ,定位速度快 ,精度高 ,可广泛用于需精密定位的控制系统。
A new control system of gel content in filament winding in oil pipelines is introduced. The system carries out precisely positioning control of gel content by applying servo motor for coarse adjustment combined with PZT for fine adjustment. The diffraction interference grating technique is utilized for the feedback of the positional signal in real time, to realize closed-loop control of the executive mechanism. The working range of 50mm can be achieved while the positioning accuracy is ±0.1μm. A single-chip computer, which communicates with the upper PC , is used as the control core of the closed-loop control system.
