摘要
提出了小水线面双体船纵向运动控制系统的数学模型,并建立了该系统的试验平台,开展了前后鳍静态和动态水动力特性试验,分别进行了无控船模和前后鳍控制船模在规则波中的耐波性试验。试验结果表明,所设计的前后鳍对该小水线面双体船具有可控性;由确定控制矩阵K的方法获得了初步优化的控制规律;经初步优化控制后的实船,在不规则波上的升沉和纵摇有义值分别下降26.9%和32.0%。
A mathematical model of longitudinal motion control system on SWATH is presented and its experimental platform is established in this paper. Using the experimental platform, the following experiments are performed, the static and the dynamic hydrodynamic characteristic experiments of fore fins and aft fins; the model seakeeping experiment of non-controlable SWATH in regular wave; the model seakeeping experiment of controlable SWATH by fore fins and aft fins in regular wave. It is concluded through the foregoing experiment researches that the fore fins and aft fins can effectively control SWATH; the method to determine control matrix K is deduced and a preliminary optimizing control rule is obtained; the significant height of heave and pitch of full scale SWATH reduces 26.9% and 32.0% respectively in irregular wave by preliminary optimizing control system.
