摘　　要：针对水翼双体船纵向运动的非线性,提出了一种基于 T-S 模糊模型的鲁棒滤波器,对水翼双体船的纵向运动姿态进行估计。建立水翼双体船运动模型的 T-S 模糊模型,将鲁棒滤波与 T-S 模糊模型相结合,建立基于 T-S 模糊模型的鲁棒滤波器,结合线性矩阵不等式求解增益矩阵,对水翼双体船的纵向姿态进行估计,并运用Matlab进行仿真。仿真结果表明,该方法是有效可行的。In this paper,a robust filter based on T-S model is proposed to estimate the longitudinal motion attitude of hydrofoil catamaran.Firstly,the T-S fuzzy model of the hydrofoil catamaran is established.Secondly,the robust observer based on the T-S fuzzy model is established by combining the robust filter with the T-S fuzzy model.Finally,the gain matrix is solved by using the linear matrix inequality.The longitudinal attitude of catamaran was estimated and simulated by Matlab.The simulation result proved that the method is effective and feasible.
