摘要

在本論文中，我們將考慮船舶航行操控系統的控制問題。因爲船舶在航行時，其操控系統模型船尾主推進器有三個非線性的自由度（縱移、橫移、平擺）會互相干擾，故此操控系統的非線性控制器設計問題頗受注意。本論文中將使用Takagi-Sugeno(T-S)模糊模型將船舶航行操控系統建模。使用線性矩陣不等式(LMI)的設計技術，我們可由船舶航行操控系統模型設計出非線性的模糊控制器。最後，本論文所提模糊控制技術之實用性可由模擬的結果表現出來。

The control problem of ship steering systems is considered in this paper. Since the model exhibits nonlinear interaction in three degrees of freedom (surge, sway, and yaw) by means of main propellers aft of the ship. This control problem interests as a case which study in nonlinear controller design. The ship steering system considered in this paper is modeled by a Takagi-Sugeno (T-S) type fuzzy model. Applying Linear Matrix Inequality (LMI) design technology, we can design a nonlinear fuzzy controller for the T-S type ship steering systems. Finally, the utility of the present fuzzy control approach can be demonstrated by the simulation results.
