【摘要】：由于船舶航行時(shí),受到海浪、海風(fēng)、海流等隨機(jī)擾動(dòng)的影響,這些擾動(dòng)以海浪引起的橫搖運(yùn)動(dòng)最為顯著,卻無法直接測量.船舶的裝載狀態(tài)和船速的變化,使船舶運(yùn)動(dòng)的數(shù)學(xué)模型存在參數(shù)不確定性,在考慮前兩種情況下,建立船舶橫搖隨機(jī)系統(tǒng)的不確定數(shù)學(xué)模型,設(shè)計(jì)魯棒濾波器,利用李雅普諾夫穩(wěn)定性理論推導(dǎo)出使系統(tǒng)均方漸近穩(wěn)定且滿足魯棒H∞性能的濾波器存在的充分條件,通過標(biāo)準(zhǔn)數(shù)值軟件進(jìn)行求解及仿真,驗(yàn)證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，
