After fractional order differencing, the long momory series of dowjones index and nasdaq index become stationary, but the fractional order of two indexes is different, so there does not exist linear cointegration relation between them
摘要首先對道瓊斯工業指數進行分整分析，長記憶的道指被分數維差分得到平穩時間序列；進而對納指也進行分數維差分。 -
In addition, the approximate formula for coefficient k p, ki, kd is also suggested by using characteristic index of forecast control. finally, through emulation, the fractional - order pi ~ d ~ arithmetic is compared with the integer - order pid arithmetic. the availability of the strategies and stability of systems are proved by doing some analysis and simulation
然後利用根軌跡的方法分析了擁塞控制系統的穩定性，並在此基礎之上採用廣義預測控制方法所應用的特性指標求出了k _ p ， k _ i ， k _ d的近似計算公式。 -
Third, to make the vehicle meet the performance index in full flight envelop, a h gain - scheduled controller based on linear varying parameter ( lpv ) system are designed. a lpv plant with a linear fractional dependent variable can be represented by upper lft ( linear fractional transformation ) interconnection. with this technique, the overall control problem can be transformed to a traditional robust control problem, and the ultimate results are given by solving a series of linear matrix inequalities ( lmis )
通過把非線性系統簡化為了線性變參數系統（ lpv ） ，再有通過線性分式變換（ lft ）將lpv系統轉化為一個線性定常系統和不確定性組成的lft互聯形式，使之轉換成為一個經典魯棒控制問題，然後通過求解一組線性矩陣不等式（ lmis ）得到變增益h _控制器。
