A simple active RC circuit is given to synthesize the low- pass type of second order transfer function. The damping ratio is easily adjusted without changing the value of undamped natural frequency. An experimental example is given to illustrate the simple design procedure.

In this paper, we propose a novel Petri Net model for solving test generation and site of fault and fired logical value for combinational circuits. In order to improve the logic fault efficiency, the transitions of general Petri Nets (PNs) are modified according to the critical of truth table, called Logic Petri Net LPN. The LPN model can transfer complexity circuit problem to a local adjacent place and transition relational problem. Therefore, the site of fault and fired logical value problem is simplified and clearly. The LPN model has the properties of Boolean algorithm, collapsing fault with clear physical concepts, fast calculation speed, and high veracity. The approach contains site of a fault and fired logical value reasoning algorithm and test vector generation reasoning algorithm, Two examples are shown to demonstrate the effectiveness of our approach.

本計劃的主要內容是分析中華衛星一號(ROCSAT-1)上有關粗型太陽感測儀(Coarse sun sensors)的感測資料及異常行為。並且探討如何由粗型太陽感測儀所獲得的資料來估計太陽位置的方法並建立正確的計算模式。最後提出新的測定方法來改善粗型太陽感測儀的效能，除了能使衛星保持正常運作之外，期望能得到精準度更高及可靠性更好的衛星姿態定位系統。本計劃的實施要點分述如下： 1.對於目前中華衛星一號的粗型太陽感測儀運作與異常情形作一探討。其次利用感測器量測的即時資料來分析誤差對於太陽定位所造成的影響，並且確定可能改進的方向。 2.分析粗型太陽感測儀運作的所有可能方式與結果，並討論對於太陽定位與姿態判定的影響。 3.參考相關文獻、技術報告及衛星感測資料以建立基本數學模式，並且利用此模式來計算太陽位置與衛星姿態。 4.提出新的演算法來改善粗型太陽感測儀的效能，完成太陽定位及衛星姿態系統的模擬分析，並且與衛星感測資料相互比較，以驗證新演算法的可行性。 5.完成計劃報告書及軟體程式碼。
