| 摘 要： | 针对某导管架平台电液调平系统多缸运动同步控制问题,引入最小相关轴数控制思想,基于相邻交叉耦合控制和滑模变结构控制理论,设计了多缸运动同步控制器,该同步控制器由1个单通道跟踪误差控制器和2个相邻同步误差控制器构成.对单通道子系统中由于长管路存在导致的时延问题,提出了一种具有滑模预估结构的误差跟踪控制器,并以四缸运动同步控制系统为例进行了仿真研究,结果表明该同步控制方法具有较好的控制效果和较强的鲁棒性,证明了方法的有效性.

| Abstract: | In order to solve the multi-cylinder movement synchronization problem of an electro-hydraulic leveling system for offshore jacket platforms,a position synchronization control strategy based on the least correlative axis control was developed by employing the adjacent cross coupling control structure and sliding mode variable-structure control method.The synchronization controller was composed of a one-channel tracking error controller and two adjacent synchronous error controllers.Due to the time delay of a single channel caused by a long pipeline,a tracking error controller with a sliding mode predictor structure was designed.The simulation results of the four-cylinder movement synchronization control system show that the tracking error controller and synchronization controller have better robustness and demonstrate the effectiveness of the proposed method. |
