Design of TS-Fuzzy-Model-Based Time-Delay Control Systems Using an Integrative Computational Method

[[abstract]]本論文首先提出一種新的正交函數計算法來求解Takagi-Sugeno (TS) 模糊模型動態時延方程式。所提出的新方法，不需經由複雜的微分與積分計算，僅包含矩陣代數的運算，因此有助於電腦的運算過程可簡易並快速地完成，同時也可降低運算的複雜度。然後，舉一數值例來驗證所提出之正交函數計算法的有效性。接下來，使用正交函數計算法將TS模糊模型動態時延控制系統的穩定二次有限時間最佳平行分配補償控制的設計問題，轉換成由代數方程式型態來表示的靜態最佳化問題，而在論文中之二次有限時間積分的性能指標，同樣也以正交函數計算法轉換成矩陣代數的型式，如此可簡化設計的複雜度，也有助於後續田口基因演算法的應用，並配合由線性矩陣不等式技巧所推導出的時延依賴穩定充分條件，共同來解決TS模糊模型動態時延控制系統的穩定二次有限時間最佳平行分配補償控制器的設計問題。文中也將針對上述的穩定二次有限時間最佳平行分配補償控制器的設計問題，舉出實例模擬說明，所提出之新設計方法的應用可行性。最後，針對時變TS模糊模型動態時延控制系統之穩定二次有限時間最佳模糊平行分配補償控制器設計問題，應用凸集合的概念與線性矩陣不等式技巧，推導出時延依賴穩定充分條件，再與正交函數計算法和田口基因演算法結合，在二次有限時間積分性能指標最小化的控制目標下，設計時變TS模糊模型動態時延控制系統的穩定二次最佳模糊平行分配補償控制器，並舉一設計例，來驗證本文所提出之設計方法的應用情形。[[abstract]]In this dissertation, the orthogonal-functions approach (OFA) is first proposed to solve the Takagi-Sugeno (TS) fuzzy-model-based time-delay dynamic equations. The new method simplifies the procedure of solving the TS-fuzzy-model-based time-delay dynamic equations (TSFMTDE) into the successive solution of a system of recursive formulae only involving the matrix algebra. The new proposed approach is non-iterative, non-differential, non-integral, straightforward, and well-adapted to the computer implementation. The computational complexity can therefore be reduced remarkably. An illustrated numerical example is given in order to demonstrate the availability of the presently proposed method. Next, for the finite-horizon optimal control problem of the TS-fuzzy-model-based time-delay control systems, by integrating the delay-dependent stabilizability condition, the OFA, and the hybrid Taguchi-genetic algorithm (HTGA), an integrative method is presented to design the stable and quadratic-optimal parallel-distributed-compensation (PDC) controllers. In this dissertation, the delay-dependent stabilizability condition is proposed in terms of linear matrix inequalities (LMIs). The control objective of quadratic optimal fuzzy PDC controllers is to minimize a quadratic integral performance index, where the quadratic integral performance index is also converted into the algebraic form by using the OFA. Based on the OFA, the stable and quadratic-optimal PDC control problem for the TS-fuzzy-model-based time-delay control systems is replaced by a static parameter optimization problem represented by the algebraic equations with constraint of LMI-based stabilizability condition; thus greatly simplifying the stable and optimal PDC control design problem. The computational complexity for both differential and integral in the stable and optimal PDC control design of the original dynamic systems may therefore be reduced considerably. Then, for the static constrained-optimization problem, the HTGA is employed to find the stable and quadratic-optimal PDC controllers of the TS-fuzzy-model-based time-delay control systems. A design example of the stable and quadratic-optimal PDC controllers is given to demonstrate the applicability of the proposed approach. Finally, for the finite-horizon optimal control problem of a class of time-varying TS-fuzzy-model-based time-delay control systems, by complementarily fusing the OFA, the HTGA and the delay-dependent stabilizability condition, an integrative method is presented to design the stable and quadratic-optimal PDC controllers, where the delay-dependent stabilizability condition can be derived from the concept of convex sets and the LMI technique. A design example of the stable and quadratic-optimal PDC controllers of a class of the time-varying TS-fuzzy-model-based time-delay control systems is given to demonstrate the applicability of the proposed new integrative approach

Study on Electromagnetic Characteristic Compensation in Remote Field Eddy Current Testing

[[abstract]]遙場渦電流(Remote Field Eddy Current，RFEC)檢測技術已被廣泛的應用於換熱器管束的檢測，依據從RFEC檢測換熱器管束的經驗中，發現碳鋼管常會因製造與處理過程的不同，以及使用環境的改變，導致本身材質發生變化並使得管子的電磁特性隨之改變。所以在檢測時若沒有對此材料的電磁特性進行補償，就會產生評估誤差。本文利用RFEC的集膚深度理論(skin-depth theory)及RFEC訊號在電壓平面(voltage plane)上的幾何關係，推導出一個數學理論模式，依此數學理論模式建立的新評估曲線(evaluation curve)來補償因管子的電磁特性改變所造成的誤差。經由理論的推導及實驗驗證結果得知此種方法具可行性，所以除了使用頻率調整方式來進行補償外，此數學理論模式對現場檢測之技術人員而言是另一種新的選擇。此方法亦可以提供手邊沒有適當之標準管材時的另一種解決方式。[[abstract]]The Remote Field Eddy Current (RFEC) has been comprehensively applied to detect the wall loss of ferromagnetic tube. According to our experience, we found the problem of variation of material electromagnetic characteristics occurred on the carbon steel tube was often occurred in practice. Therefore, if we fail to compensate the change of electromagnetic characteristics during inspection, the error of evaluation will be generated. This study applied the skin-depth theory of RFEC and geometric relationship on voltage plane for deriving a compensatory model of mathematical methodology. The new evaluation curve established on the basis of this mathematical methodology is to compensate the error contributed by the change of electromagnetic characteristics in the tube. The method offered by this study has been proved to be reasonable, feasible and acceptable through the process of derivation and testing result

Study of Persimmon Dehydration Using Dehumidification Method

本省柿餅製造多在陽光下吹風晾乾，其製程曠廢時日，若受陰雨氣候影響，常有30至70％腐爛率，對果農損失極大，以烘乾機製造柿餅，則有厚皮且脫澀不完全現象。為解決柿餅製造過程中因雨導致之大量腐敗，並製造出優良品質之柿餅，本研究將總量935公斤之柿青，分四批先後逐日置於控制溫濕度之乾燥室中（28-30.5℃、RH 48.3-69.8%)，約經過5個單元循環操作（每個循環為除濕18小時，停機6小時）可以製成柿餅，其較自然日曬法約快兩天。除濕乾燥室中之除濕機除濕能力不足時，會導致乾燥室中濕度上升，隨後發生腐爛，此現象出現在柿青進行乾燥之第三或第四天，即柿子果實開始成熟軟化時。以除濕乾燥法製造柿餅，可以得到與日曬乾燥法所製相同之柿餅色澤，且其色澤呈現均一誘人之金黃色。果糖、葡萄糖為柿餅中主要之糖類，其在乾燥過程中因水分份蒸發而濃度增加，其中又以自然日曬法者較高。柿餅之硬度在除濕乾燥四天後達到最高之530克，自然日曬法製得之柿餅則在乾燥約七天後才達到相同之硬度。柿餅乾燥過程中水活性持續下降，但仍未達常溫下可以保存之程度。 Dehydration of persimmons (Diospyros kaki L.) using dehumidification method at the range from 30℃ to 35℃ and 50 to 65% relative humidity environment resulted in the highest yield and the best quality of dehydrated persimmons, as compared to the products made from conventional sun drying method. Dehumidification of persimmons at above conditions for 18 hours and then turn off the dehumidifier for six hours was the best operation condition for persimmon moisture balance and case hardening prevention. The dehumidification process took five days to remove about 61.3 % moisture of the persimmon. It is two days shorter as compared to sun drying method. Texture of the persimmon decreased to the lowest strength within two days due to fruit softening, and then gradually increased due to water removal and skin formation of dehumidified persimmon. The dehumidified persimmon showed golden color appearance as that by sun drying. Glucose and fructose were the main sugars of persimmon, both of those sugars increased during the drying process. Sun drying persimmon showed a higher amounts of glucose and fructose than the dehumidified persimmon

Studies of Hsian-tsao (Mesona procumbens Hemsi.) Gelling Constituents Extraction and the Gel-forming Properties of Hsian-tsao Extracts

仙草(Mesona procumbens Hemsi.)是一種含有具凝膠性多糖類物質之草本植物，其經過適當鹼量添加與熬煮所得之萃取液，在添加2％澱粉時，會有韌性極強之凝膠特性。本研究比較仙草萃取時，添加0.05、0.1、0.3、0.5、0.7、l.0、1.2、1.4％碳酸鈉、碳酸氫鈉對仙草多糖類物質萃出之影響，結果顯示碳酸鈉處理之乾物抽出率與全可溶性固形物分別在19.32至44.85％與1.8至4.6ºBrix間，添加碳酸氫鈉萃取處理之乾物抽出率、全可溶性固形物則分別在13.90至38.95％與1.3至4.9ºBrix間，此顯示兩種鹼類皆有助於使仙草組織崩解並釋出其中之多糖類物質，而碳酸鈉處理較碳酸氫鈉處理對仙草植物中多糖類物質有更佳之抽出效果。又添加愈高量之碳酸鈉、碳酸氫鈉處理，會有愈多之仙草多糖類物質被抽出。綜合所製成仙草凍之凝膠品質、風味及口感，顯示以添加0.3至0.5％之碳酸鈉濃度進行萃取為最佳。 為比較碳酸鈉與碳酸氫鈉處理所得萃取液之凝膠性質，將此兩種鹼類處理所得之萃取液分別稀釋為含0.6、0.8、1.0、1.2、1.4％固形物之仙草溶液，再分別添加2.0、2.5、3-4.0％之小麥澱粉，各處理均顯示添加0.3％或0.5％碳酸鈉、碳酸氫鈉之萃取處理有最高之凝膠強度，其凝膠強度分別在42.0至130.0克／平方公分與36.3至110.6克／平方公分間，顯示以碳酸鈉處理所得之萃取液有較佳的凝膠品質；提高澱粉濃度有使仙草凝膠強度增加之趨勢，濃度以2.0-3.0％澱粉處理較宜，因添加4.0％小麥澱粉處理仙草凍之質感較差。 Hsian-tsao gel is a jello-type dessert popularly consumed in the Far East countries. The gel is prepared from the alkaline extract of Hsian-tsao (Mesona procumbensHemsl.) herb with the addition of approximately 2 % starch at boiling temperature. A dark-brownish gel will be formed after the solution is cooled. Extraction of Hsian-tsao gelling constituents using sodium carbonate and sodium bicarbonate at concentration ranged from 0.05 % to 1.4 % for 3 hours resulted in the total solids recoveris of 19.3 to 44.8 % and 13.9 to 39.0 %, respectively. These results are significantly higher than 12.2 % total solid srecovery of the herb extracted with distilled water. The higher concentration of sodium carbonate or sodium bicarbonate solution the more total solids is yielded. Hsian-tsao gels prepared from 1.0 Brix 0.3 % or 0.5 % sodium carbonate or sodium bicarbonate extracts with 2.0 % wheat starch added resulted in the most acceptable gel strength of 80 g/cm2. The higher the concentration of extract and the higher the starch added to the extract formed the greater gel strength of the gel
