气囊支撑浮筏隔振系统姿态控制研究

将气囊隔振器应用于舰船浮筏隔振装置，通过控制气囊充、排气可实现浮筏的姿态调整。目前以气囊工作高度为指标的控制方法，存在各个气囊压力分布不均和调节过程振荡的问题，针对该问题提出一种基于气囊工作高度、实际压力与最优压力偏差的浮筏姿态控制策略。将调整分为高度调整和水平姿态调整2个阶段：首先采用模糊控制快速将输出轴调整到对中高度，然后以"高排低充"的策略精确调整浮筏水平姿态。试验结果表明，该控制策略能更加快速、平稳、精确地调整浮筏姿态。

Research on attitude control of floating raft vibration-isolation system with air spring

Air springs are equipped on ship floating raft vibration isolation system, and the attitude adjustment of float-ing raft can be realized by controlling the air bag charging and discharging. To solve the control problem of pressure distribu-tion and raft oscillating in the course of raft's attitude adjustment, an control strategy is proposed based on air spring's height and press, which contains two stages:first, output shaft alignment is achieved using fuzzy control;then, using a strategy of 'high-discharge or low-charge' to adjust the horizon attitude precisely. Tests are carried out to verify the efficacy of this strategy, and the test results indicate that the designed control system is effective.
