【摘要】：由于船舶航行时,受到海浪、海风、海流等随机扰动的影响,这些扰动以海浪引起的横摇运动最为显著,却无法直接测量.船舶的装载状态和船速的变化,使船舶运动的数学模型存在参数不确定性,在考虑前两种情况下,建立船舶横摇随机系统的不确定数学模型,设计鲁棒滤波器,利用李雅普诺夫稳定性理论推导出使系统均方渐近稳定且满足鲁棒H∞性能的滤波器存在的充分条件,通过标准数值软件进行求解及仿真,验证所采用方法的有效性及可行性.
[Abstract]:Due to the influence of random disturbances such as wave, wind, current and so on, the rolling motion caused by the waves is the most obvious, but it can not be measured directly. The ship's loading state and ship speed change. Considering the first two cases, the uncertain mathematical model of ship rolling stochastic system is established, and a robust filter is designed. By using Lyapunov stability theory, sufficient conditions for the existence of filters which make the mean square asymptotically stable and satisfy the robust H 鈭，
