摘要
为了提高船舶减摇效果,研究了舵/鳍联合减摇鲁棒控制问题.通过提出广义输出干扰的概念,将舵/鳍联合减摇控制系统广义对象的奇异控制问题转化为非奇异标准控制问题,给出了艏摇/横摇耦合运动的线性分式变换模型和广义对象状态空间实现.基于μ综合设计了舵/鳍联合减摇H∞鲁棒控制系统的控制器,并用结构奇异值理论对所设计的系统进行鲁棒稳定性和鲁棒性能分析.通过数字仿真,证明了所设计的控制系统具有良好的减摇效果和鲁棒性.
To improve the effectiveness of roll damping on ships, robust damping of roll with joint rudder/fin controls was researched. Using the concept of a generalized output disturbance, we converted the multiple controls of the many generalized objects in a rudder/fin joint roll damping control system into a problem of a nonsingular standard control. The linear fractional transform model of yaw/roll coupling movement and the realization of generalized object state space are given. The controller for H~ robust control system of rudder/fin joint roll damping was de- signed based on μ -synthesis, and the structured singular value theory was used to analyze robustness of stability and performance for this system. A digital simulation proves that the system has good roll damping efficiency and robust performance.
