船舶在海上航行时,不可避免会受到海风、海浪、海流的环境干扰,会产生艏摇、横摇等现象,影响船舶的适应性,产生诸多不利影响。针对船舶的横摇减摇控制系统的数学模型,在考虑系统的非线性和参数不确定性的情况下,利用李雅普诺夫稳定性理论推导使系统渐近稳定的充分条件,设计鲁棒控制器,用MATLAB软件进行求解和仿真,验证方法的可行性。

As a ship is sailing in sea, its adaptability will be affected by yawing and rolling as well as other inevitably influ-ence caused by wind, waves and ocean current. To design robust controller in accordance with the model of ship roll and anti-roll-ing systems, this paper takes nonlinearity and parameter uncertainty into consideration, deduces the conditions for systems stabili-ty with Liapunov’s Stability Theory and tests its feasibility through solution and stimulation with the help of MATLAB ( Matrix La-boratory) .
