| 摘 要： | 针对吊艇架减摆系统,设计了减摆罩基于母船横摇、纵摇两个自由度的解耦的阻尼结构,使阻尼器的减摆作用相互独立,互不影响。建立了该种减摆结构的数学模型,提出了利用船舶摇摆谱密度对数学模型进行了统计线性化分析,通过最优计算得出最优阻尼阀开口,针对被动减摆装置的局限性,利用模糊方法设计了最优阻尼的半主动控制策略。

| Abstract: | tThe active pendulation control is proposed based on backstepping for three-dimensional underactuated davit system. This paper establishes a three-dimensional dynamics model of davit, and designes the anti-swing control device of davit by backstepping. Through optimal calculation of optimal damping we get the optimal opening of valve.Aiming at the limitation of passive anti-sway device, the fuzzy method is used to design the optimal damping semi-active control strategy.Simulation results show that the pendulation controller has a good effect on anti-swing. |

| Keywords: | davit optimal calculation semi - active anti-sway control |
