近年來模糊理論與類神經理論已在廣泛的應用在各個領域中,本文利用類神經的自我學習能力,應用倒傳遞類神經網路,結合模糊的架構,來設計一個類神經-模糊的避碰系統。應用類神經的自我學習模式,調整模糊控制中的歸屬函數之中心點及寬度,以期避碰系統可以更迅速地將所建議之船艏角傳達給自動操舵系統,而達到避碰效果。
由於 控制理論具備排除系統不確定性及干擾的優越能力,本文設計一個類神經- 的自動操舵系統,即於在 控制系統中,加入類神經之自動學習功能,以加速 觀測器之收歛速度,使自動操舵系統,可以更有效的追蹤避碰系統所建議之船的航向角度。本研究把類神經-模糊的避碰系統與類神經- 的自動操舵系統做整合,形成完善的避碰理論,最後再以各種避碰遭遇狀況做電腦模擬,分別以障礙物避碰及船舶避碰做模擬,以驗證本文理論的可行性。
Abstract
Experts’ experiences and International Collision Avoidance Rules are two of the urgent information required in designing the ship collision-avoidance systems and both of them are in the linguistic form. Since the fuzzy system can provide a linguistic framework for handling system uncertainties, a fuzzy-based collision-avoidance system is studied in this paper. To select the number of inference rules and the input-output membership functions in a fuzzy system more efficiently, a systematic fuzzy collision-avoidance system is proposed in this study. To perform the ship task of collision-avoidance effectively, a robust autopilot based on H∞-control methodology and neural strategy is designed to form the proposed neural-H∞autopilot system. The neural-network learning algorithm used in this study is able to increase the speed in finding the H∞-optimal controller of the autopilot. Computer simulation results of a ship model reveal that the proposed neural-fuzzy collision-avoidance system works well when the suggested collision-avoidance route is executed by the designed neural-H∞autopilot system.
