3000 m钻井平台波浪补偿控制系统研究

Simulation of Wave Compensation Control System for 3000 m Drilling Platform

针对钻井平台波浪补偿控制系统,运用意大利ATOS公司的高性能三位四通电液比例换向阀和天车主动油缸来构造钻柱升沉补偿装置的传递函数,提出一种参数自适应模糊PID集成控制策略. MATLAB/Simulink仿真结果表明,该控制系统性能稳定,可以补偿平台94. 3%的升沉运动,补偿精度较高,为搭建3 000 m深海钻井平台波浪补偿装置可行性提供了可靠的理论依据.

According to the shipyard drilling platform wave compensation control system, Adopting the highperformance three position four way electro-hydraulic proportional reversing valve of Italy ATOS company andactuating cylinder is consist of transfer function of drilling column heave compensation device,put forward integratedcontrol strategy based on a parameter adaptive fuzzy PID,the system simulation analysis using MATLAB / Simulinksoftware. The results show that the control system is stable and the compensation accuracy is high. It cancompensate the heave motion of platform 94. 3%. and provide a reliable theoretical basis for the feasibility of thewave compensation device of 3 000 m deep water drilling platform.
