中文摘要： 项目以穿浪双体船纵摇/升沉-水翼/尾板联合控制为工程背景。针对穿浪双体船在高速迎浪行驶时，容易受到外界如风、浪、流等的干扰，使船的纵摇/升沉运动剧烈这一问题，深入分析问题产生机理，首次提出水翼/尾板联合控制思想来改善穿浪双体船的纵摇/升沉运动。通过建立襟尾翼/尾压浪板水动力模型、在线襟尾翼/尾压浪板角并行遗传优化、引入智能控制策略及同步控制策略，实现能耗指标约束下穿浪双体船的水翼/尾板任意转角比联合控制，可保证所设计的控制器在穿浪双体船的整个航速范围都有稳定输出，降低系统控制器的保守性，并提高控制性能，节省能耗。 项目致力于获得一类非线性系统分析和综合的新方法，降低系统设计保守性。同时，旨在更好地解决穿浪双体船纵摇/升沉控制实际应用问题，促进我国高性能船舶现代化装备进程。因此课题具有重要的理论研究价值和实际应用意义。

英文摘要： This project mainly studies pitching/heave-hydrofoil/stern flap joint control for wave-piercing catamaran as project background. According to wave-piercing catamarans sailing with high speed in head sea, they are affected easily by external interference, such as wind, waves, currents, leading to serious pitching / heave motion. The generation mechanism of this problem is analyzed in-depth first. Then hydrofoil/stern flap joint control strategy is proposed to improve pitching/heave motion of wave-piercing catamaran. Under the constraint of energy consumption index, any rotation angle ratio of hydrofoil/stern flap joint control for wave-piercing catamaran is achieved by establishing the hydrodynamic model of hydrofoil/stern flap by introducing intelligent control strategy and synchronization control strategy. The controller designed in the project with a stable output in the entire speed range of wave-piercing catamaran can be ensured. The conservative of system controller is decreased and control performance is improved. The energy consumption is saved. This project aims to obtain new methods for a class of nonlinear systems analysis and synthesis to decrease the conservative of system design. Moreover, This Project aims to solve the practical application problem of wave-piercing catamaran pitching / heave contro
