减摇鳍/水舱联合减摇系统模糊自适应滑模控制

针对减摇鳍和被动式减摇水舱设备在不同航速下的减摇特点,建立了船舶减摇鳍/水舱联合减摇系统的横摇数学模型。结合模糊自适应控制良好的逼近特性和滑模控制算法对扰动和模型参数变化的不灵敏性,设计了减摇鳍/水舱联合减摇系统的模糊自适应滑模控制器。采用实船参数的仿真结果表明,所设计的控制器具有良好的自适应性和鲁棒性,减摇鳍/水舱联合减摇控制系统在不同海况和不同航速下均具有良好的减摇效果。

Research on Fuzzy Adaptive Sliding Mode Control of Fin/tank Joint Roll Stabilization System

In order to achieve a great roll stabilization effect of ships at all-speed, the rolling mathematical model of fin/tank joint roll stabilization system is established according to the roll stabilization characteristics of fin stabilizer and passive anti-rolling tank equipment at different speeds. Combining the good approximation characteristics of fuzzy adaptive control with the insensitivity of sliding mode control to disturbance and model parameter changes, the fuzzy adaptive sliding mode controller for fin/tank joint roll stabilization system is designed. The simulation results using real ship parameters show that the designed controller has good adaptability and robustness, fin/tank joint roll stabilization control system has good roll stabilization effect under different sea conditions and speed.
