中文摘要：
为了在保持航向的同时,提高船舶减摇效果,设计一种舵鳍联合控制系统.针对给定的线性舵鳍联合系统,根据性能的要求,对其选择权函数进行成形,然后利用H∞回路成形算法对成形后的系统设计鲁棒控制器,采用Hutton提出的降阶法对控制器进行降阶.通过Matlab中的Simulink工具箱分别对6级和8级风浪作用下考虑到舵机、鳍机的舵鳍联合控制系统进行仿真.仿真结果表明所设计的控制器在保持航向的同时能达到较好的减摇效果,并且该控制器具有较强的鲁棒性.
英文摘要：
To make the ship improve the control effect of roll-damping with good course-keeping, a kind of rudder/fin joint control system was designed. Considering the demand of performance for the given rudder/fun joint system, it was shaped though selecting weight functions, then a robust controller was designed based on the algorithm of loop shaping. Under Beaufort No. 6 and 8 sea states, the rudder/fin joint control system with rudder/fin servo systems was implemented using Simulink. Simulation results show that the designed controller has nice robust performance on course-keeping and roll stabilization.
