摘　　要：分析了水翼艇的运动方程并通过适当的假设将其线性化,建立水翼艇纵向运动状态空间方程,同时给出了系统状态的测量方程,运用卡尔曼滤波对其纵向运动进行滤波。文中同时给出了MATLAB仿真计算结果,分析其方差和最大误差,验证了结果的正确性。The article analyzed the motion equations of the hydrofoil and linearization them based on suitable suppositions. It also established the state space equations of longitudinal motion of the hydrofoil, gave the system mode survey equation and filtered to the longitudinal motion based on Kalman filtering. Simultaneously, the article had given the MATLAB simulation computed result and analyzed its variance and the biggest error which confirmed the result accuracy.
