摘　　要：为实现海洋钻井用升沉补偿装置的国产化,采用相似原理设计了海洋钻井平台钻柱升沉补偿试验台控制系统。该系统采用电液比例换向阀控制不对称液压缸模拟海浪升沉,可对升沉运动进行钻柱补偿控制;由于控制部件采用的电液比例换向阀存在死区,系统采用PID和死区补偿控制算法,较好地实现了海浪模拟和补偿控制。为保证升沉给定和跟踪控制精度,软件采用VB调用API函数,可对采样时间间隔进行精确控制。试验数据表明,该控制试验台可满足浮式钻井平台钻柱升沉补偿系统控制要求。To achieve the localization of the heave compensation device for offshore drilling, the similarity principle was adopted to design the control system for the drill string heave compensation test bed. The system uses the electro-hydraulic proportional reversing valve to control the asymmetrical hydraulic cylinder to simulate the heave movement of waves. It can carry out the drill string heave compensation control. Due to the fact that there exists a dead zone within the valve adopted by the control parts, the system adopts the PID and dead-zone compensation control algorithm, thus achieving a better simulation and compensation control of waves. To ensure the accuracy of the heave set and the tracking control, the software uses the API function in VB. It can make a precise control of the sampling interval. The experimental data show that the control test bed can satisfy the control requirement of the drill string heave compensation system of the floating drilling platform.
