船 舶 穩 定 翼 控 制 系 統 設 計 之 研 究 *陳文慶 ** 周顯光 **鍾豐仰 *帕司卡企業有限公司 **聯合船舶設計發展㆗心 摘 要 船舶穩定翼控制系統為㆒利用調變穩定翼的攻角以獲得所需之力與力矩來達到船舶在波浪 ㆗航行時抑制搖晃的裝置，其以大出力之電液伺服系統為驅動力。然因為船㆖的真實環境較惡 劣，訊號傳輸時容易產生電磁的干擾，影響控制系統的可靠度；而且㆗央控制電腦的效能及穩定 性亦影響船舶運動的安全性。 本研究以具高效能及高穩定性之 real-time Linux(為㆒種即時 UNIX 作業系統)為㆗央控制電腦 的作業平臺，並以 RS-485 做為㆗央控制電腦與電液伺服系統控制電路間之傳輸介面，取代㆒般 類比訊號傳輸以減少干擾，以對整個控制系統做更安全的考量。另外，針對船舶運動特性，設計 ㆒個具有強健性之自組織模糊控制器以適時調變穩定翼之攻角，達到抑制船舶搖晃之效果。最 後，再對整個控制系統的軟、硬體作㆒實船整合測試，以驗證系統之穩定性與可靠度。 關鍵詞：穩定翼、減橫搖、自組織模糊控制、即時系統 STUDY ON THE DESIGN OF CONTROL SYSTEM FOR SHIP STABILIZERS W.C.Chen* S.K.Chou** F.Y.Chung** Pascal Sys. Eng. Co, Ltd United Ship Design Development Center Anti-rolling Self-Organizing Fuzzy Control Real-time Linux Keywords: Stabilizers 、 、 、 ABSTRACT Ship stabilizers control system is commonly applied to a ship to reduce the rolling and pitching motion when sailing in waves. The stabilizer is high power electro-hydraulic servo system. Due to noises(EMI) of the power system, the stability and efficiency of the control computer for the stabilizer system is critical to the safety of the ship motion. The real-time Linux operating system and an interface using RS-485 to communicate between the control computer and the electro-hydraulic servo system will be setup. We will also design a self-organizing fuzzy con- troller to control the stabilizing fins in real time. Finally, we will test the entire control system by experiments on the ship to prove the effectiveness of the hardware and software. ㆒ 、前 言 船
