摘　　要：在分析已有海洋钻井平台、钻探船的升沉补偿系统特性的基础上,依据中国大洋协会(COMRA)的大洋多金属结核中试采矿系统及1 km深范围海试状况,提出了双油缸主动控制升沉补偿系统设计方案,创建了该系统的虚拟样机.对该虚拟样机进行参数化设计、工作过程模拟和模糊控制仿真研究,结果表明,此虚拟系统设计方案可行;基于该虚拟样机的模糊控制策略,在仿真研究中能有效提高升沉补偿效果,达到系统设计要求.The characteristics of heave compensation systems used on a marine drilling platform or on a drillship are analyzed. An active heave compensation system with two lift cylinders is proposed according to COMRA （China Ocean Mineral Resources ＆ Association） pilot mining system for ocean poly-metallic nodule and the 1 000 -meter-deep depth sea trial status. The corresponding virtual prototype is built. The parametric design, operation process and the performance of a fuzzy logic control on this virtual system have been simulated and investigated. The results show that this designed virtual system is feasible. The proposed fuzzy control policies can improve the effect of heave compensation, and reach the design target in virtual simulation.
