中文摘要 | 本研究提出一種船模試驗方法,可以具控制器之穩定翼系統,對船艦橫搖抑制之效果。並以一模糊控制器為例,分析在穩定翼系統的適用性。本研究選擇一縮小船模,設計穩定翼翼面、機構和動力系統,以模擬實船穩定翼動作。並且設計一組可裝置此船模之感測與控制系統,其中控制器採用模糊控制法則推論。此外,本研究亦設計一組拖曳裝置,以拖曳船模定速前進,利用平面水槽,進行橫波負荷下之試驗。船模試驗結果顯示:在使用具模糊控制器之穩定翼下,對來自四種不同頻率波浪作用下,都能有效降低橫搖反應。驗證模糊控制理論適用於穩定翼系統之控制。此外,試驗結果也顯示,變更模糊控制器中歸屬函數,可改變穩定翼抑制橫搖效率,顯示將控制器與穩定翼系統同時考慮之重要性。 |
英文摘要 | Roll reduction of ships using stabilization fins with fuzzy logical controller is studied by the model test. A small active fins system, including the mechanism, power, measurement, and control device, is developed and installed on the scaled down model to simulate the action of the real ship. Moreover, a towing system is designed to pull the model by constant speed passing through the beam wave condition. The results show that the roll motion of the model is decreased more than 60% by the fins with the fuzzy logical controller for regular beam wave environment with different frequency. In addition, the fuzzy logical controller using the asymmetric membership functions can have higher efficiency than the controller using the symmetric membership functions for the stabilization fins. |
