项目摘要

"Development of a Control System for Surface Effect Ship" had been studied for two years since April 1994 to March 1996. Surface Effect Ship (SES) is supported by air cushion pressure to achieve high speed capability. Timeliness is in any case one of the most important feature for the high speed vessel, however, SES has a difficulty in keeping high speed in rough seas since the pressurized air leaks from gaps between hull and water surface.Firstly, simulator had been developed based on the MATRIXx software to investigate into the high speed performance and motion in waves. It was revealed that dynamics of SES is highly nonlinear and that nonlinear terms could not ignored even the wave height seemed so small. This made the situation worse since the control system design methodologies were based on the linear system. At it was also revealed that the louvers and fins used for the motion control of SES craft had not sufficient power for control compared with the external disturbances. This … More result in the introduction of the Bang-bang control and Fuzzy control using prompt response to the motion.This report is mainly divided into two parts ; the first one is dedicated to the speed performance and the control system to secure the deterioration in speeds of SES among waves. Secondly, the more sophisticated methodology based on the sliding mode control system design to accommodate the reasonable control system to the SES.For the first one, the estimate of speed loss in the rough sea was shown and Bang-bang and Fuzzy control methodologies were applied to provide better ride quality and to avoid speed loss to some extent. For the second one, the original modified sliding mode control was proposed neglecting the term corresponding to force to keep the state on the hypersurface. Good results were shown by the simulation not lnly for the low wave height but also for the large wave height.The system developed in this research is an very effective tool and methodology for the control system design for SES.Moreover, if this system is included in the planning stage of the new SES design, this will provide some important consideration for the general arrangement for the SES from the view point of the control of it.

“地效船控制系统的发展”研究由一九九四年四月至一九九六年三月进行，为期两年。表面效应船（SES）由气垫压力支撑以实现高速能力。时效性是高速船的重要特性之一，但由于加压空气从船体与水面之间的缝隙中泄漏，使得高速船难以在大风浪中保持高速。结果表明，SES的动力学是高度非线性的，即使波高很小，非线性项也不能忽略。由于控制系统的设计方法是基于线性系统的，这使得情况变得更糟。同时还发现，与外部干扰相比，用于SES飞行器运动控制的百叶窗和鳍板没有足够的控制功率。这 ...更多信息本报告主要分为两个部分，第一部分是专门的速度性能和控制系统，以确保在波浪之间的速度恶化的SES。其次，基于滑模变结构控制系统的设计，提出了一种适用于SES的控制系统设计方法。第一种方法，给出了在大风浪中的速度损失估计，并采用Bang-bang和Fuzzy控制方法，以提供更好的行驶品质，并在一定程度上避免速度损失。对于第二种情况，提出了一种改进的滑模控制方法，该方法忽略了与力对应的项，使状态保持在超曲面上。本研究所开发的控制系统是一种非常有效的工具和方法，而且，如果将该系统包括在新的SES设计的规划阶段，这将从控制SES的角度为SES的总体布置提供一些重要的考虑。
