中文摘要:
      受海底环境和载荷变化等因素影响,自升式海洋平台在升降过程中需实时确保平台姿态平衡问题。针对四桩腿多电机驱动自升式海洋平台的升降作业,提出一种速度-倾角偏差耦合同步控制策略。为了验证该控制策略的可行性,搭建了四桩腿海洋升降平台物理模型,根据该控制策略完成了模型升降程序设计及电气设计,并进行了样机的试验,验证了该升降系统控制策略的正确性。实现了平台升降作业时,姿态倾角保证在合理范围;若平台倾角超出安全要求,升降程序可通过对桩腿电机的速度调整,实现对平台姿态的修正,确保平台在安全范围内工作。可为海洋平台的平衡升降提供参考。
英文摘要:
      Affected by factors such as the seabed environment and load changes, the jack-up offshore platform needs to ensure the balance of the platform posture in real time during the lifting process. In this study, according to the characteristic of the jacking operation on a four-leg multimotor-driven jack-up offshore platform, a synchronous control strategy of speed-inclination deviation coupling is presented .To verify the feasibility of the control strategy, a physical model of a four-leg offshore lifting platform is built. The design of the lifting program and the electrical design are completed according to the control strategy and a prototype test is carried out to verify the accuracy of the control strategy of the lifting system. When the platform lifting operation is realized, the attitude inclination angle is guaranteed to be within a reasonable range; if the platform inclination angle exceeds the safety requirement, the lifting program can adjust the posture of the platform by adjusting the speed of the pile leg motor to ensure that the platform works within the safe range.It can provide reference for balanced lifting of offshore platforms.
