SWATH船纵向运动的区域极点配置LQ最优控制研究

Research on Regional Pole Assignment LQ Optimal Control of Longitudinal Motions of SWATH

为了改善SWATH船的纵向运动性能,并使其具有较好的鲁棒性能,采用区域极点配置LQ最优控制方法设计了SWATH船纵向运动的控制器,并利用MATLAB对控制前后SWATH船的纵向运动性能进行了仿真分析.仿真结果表明,所设计的SWATH船区域极点配置LQ最优控制器不但能够保证SWATH船的纵向运动稳定性,而且具有较好的控制性能和鲁棒性.

To improve the longitudinal motion performance of SWATH ship,and make SWATH ship have the excellent robustness,this paper designs a longitudinal motion controller of SWATH ship by using the regional pole assignment LQ optimal control method.Then,MATLAB software is adopted to simulate the longitudinal motion performance of SWATH ship before and after the controller is used.The simulation results show that the controller designed by this paper make the SWATH ship not only can keep the longitudinal motion stability,but also have the excellent longitudinal motion performance and robustness.
