摘　　要：评述了SWATH的有关运动特性问题,介绍了自动控制和运动性能评价方面开展的工作,分为三部分:1叙述航态与运动稳定性之间关系。分析SWATH航行时所产生的水动力和纵倾力矩以及SWATH的若干不稳定状态。2讨论SWATH在波浪上的运动,并用模糊数学方法综合评价其耐波性。3介绍主动控制技术的一些情况,阐明SWATH海上运动控制系统应当是波浪载荷减缓系统,并建议采用主动智能控制技术。It is a sequel paper of ＂Comment on ＂＂ （3）＂concerning with the motion behaves of SWATH. It consists of three parts. First part treats about the relations of attitude and stability. Above all, the hydrodynamical forces and moments due to the sailing are discussed. It shows that the pitching moment is a function of Fr （Froude number） and has a valley point at Fr ≌0. 4. Moreover, several unstable states of SWATH are mentioned. Part Ⅱ deals with the motion behaviors of SWATH on the waves. Fuzzy theory is used to evaluate the seaworthiness of SWATH. The results show that fuzzy theory would give the more comprehensive appreciations to researchers. In part Ⅲ , some aspects of active control technique are reviewed. It is certain that the autoriding system of SWATH should be wave load alleviation system, and an active intellectual control one would be more suitable.
