| Abstract: | 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. |
