摘要
为减少船身振动,提高其航行性能,首先建立减摇鳍水动力控制方程,并结合滑模控制理论制定相应的滑模控制策略,对船身振动进行抑制。研究表明:在同等扰动强度下,经过滑模控制的减摇鳍需要的摆动角度大大降低,具有较高的振动控制效能。同时,整个控制过程具有较高的鲁棒性,系统稳定性好。
In order to reduce the hull vibration and improve the navigation performance,this paper established the anti-rolling fin hydrodynamic control equation,and combining the sliding mode control theory to establish the corresponding sliding mode control strategy to suppress the hull vibration. Research shows that: under the same disturbance intensity,the swing angle of the fin is greatly reduced after sliding mode control,this sliding mode control has the high vibration control efficiency. At the same time,the whole control process has high robustness,good system stability.
