為了準確測量飛機油量，本論文使用虛擬感測器方法比較了直線與折曲等不同型式的虛擬探棒，將每個真實感測器的量測結果轉換為虛擬感測器的液高，實現信息融合以降低燃油體積數據庫規模，並利用形心位置較能抵消液面傾斜影響的特性，將飛行姿態範圍分成數個區間以進一步簡化對查找表的內插計算。另外，考慮到飛機油箱的不規則外型及內部的隔板結構容易影響燃油體積計算，針對研究對象的幾何特性將其進行切割並設置子油箱虛擬探棒來輔助計算。本研究分別使用Catia設計軟體與飛機地面測試的實驗數據進行驗證，確定計算的燃油體積誤差是否能符合誤差精度需求，並比較不同型式的虛擬探棒及不同解算方法的結果表現。

The primary goal of this research is to establish a fuel volume measurement method that is user-friendly and can reduce the amount of data. In order to accurately measure the fuel level of the aircraft, this paper uses the virtual sensor theory to design different types of virtual probes such as linear and curved, and convert the measurement results of each real sensor into the liquid height of the virtual sensor. With the help of virtual probe, the method can integrate outputs of every real probe and reduce the scale of the fuel tank volume characteristic database.
The centroid position has the advantage of being stable and less affected by liquid level oscillations. Using this feature to divide the flight attitude range into several intervals can further simplify the calculation of the interpolation to look-up table. In addition, considering that the irregular shape of the aircraft fuel tank and the internal partition structure easily affect the calculation of fuel volume, according to the geometric characteristics of the research object, the fuel tank is divided into several small virtual tanks and a virtual probe of the sub-tank is set to assist the calculation.
This study uses Catia design software and experimental data from aircraft ground tests to verify whether the calculated fuel volume error can meet the error accuracy requirements, and compare the results of different types of virtual probes and different calculation methods.
