摘要
对装备减摇鳍系统的舰船横摇运动的准最小方差控制、加权准最小方差控制进行了研究,在计算机上进行了数字仿真,并与目前工程上使用的PID控制进行了比较.结果表明:舰船横摇运动的准最小方差控制与加权准最小方差控制均可获得令人满意的效果.
Quasi-minimal variance control and weighted-quasi-minimal variance control for roll attitude of ship with stabiliser fin are studied in this paper.Digital simulation is carried out with computer, and it is compared with PID control used now in engineering.It is shown that satisfying results can be obtained by means of quasi-minimal variance ccontrol and weighted-quasi-minimal variance control for roll attitude of ship.
