滑模变结构理论在船舶减摇鳍中的应用

Application of sliding mode variable structure theory in fin stabilizer

以船舶减摇鳍控制系统为研究对象,将滑模变结构理论应用于船舶减摇鳍控制系统,提出一种减摇鳍滑模变结构控制器并完成该控制器的理论实现;基于船舶横摇运动的线性方程,对不同浪向下的船舶横摇运动进行系统仿真。结果表明:与常规PID控制相比,滑模变结构控制器具有更好的控制效果和更强的鲁棒性。

Taking the control system of fin stabilizer as study subject, a sliding mode variable structure controller for fin stabilizer is proposed and is put into practice with the application of sliding mode variable structure theory. It simulates the ship roll motion under different wave orientation conditions by using linear equations. The results indicate that the sliding mode variable structure controller is better and more robust than general PID controller.
