In addition, we often encounter a general problem - it is very difficult to describe a complex shape with a single bezier curve precise. method of bezier definites shape of curve, which is global project. if you locally modify curve, it is necessary to affact the global. it is that method of bezier has character of global control, but it has not charater of local control. by way of arbitrary partition. arbitrary degree elevation, that may increases control point. increases potential active character of controling curve. therefore, the thesis discusses mainly the problem of local free - form deformation, which may make bezier curve deform continuely and gain wanted figures. however, no matter what free - form deformation based on extension factor for parametric curve or arbitrary partition will reduce smoothness of parametric curve
另外，我們經常會遇到一個普遍問題，就是難以用單一的貝齊爾曲線段描述復雜的形狀。貝齊爾方法對形狀的定義是整體方案，欲對其作局部修改，必然會影響到整體，即貝齊爾方法是有整體控制性質，但卻缺乏局部控制性質。通過任意分割和任意升階得出所要變形的一段，以及增加控制點，增加對曲線進行控制的潛在靈活性。 -
These extension control ways based on different character variable represent the method of combined radiate thought and convergent thought in extension logic
方案的研究的過程充分體現了可拓學中的把發散方法與收斂方法結合的思維方式。 -
Then relation function that is a very important notion and the basic concept of extension control is imported. the thesis discusses the structure, the theory and the design method of extension controller. by this method linear, large time - delay and non - linear objects are simulated whose system character variables are error and error differential
本論文系統地介紹了可拓學的理論框架、可拓集合論、物元的概念、物元變換的理論，並引入了關聯函數這一重要概念，接著介紹了可拓控制的基本概念和可拓控制器的結構和原理，運用可拓控制器的設計方法，以偏差和偏差微分為系統特徵量分別對線性對象、大延時對象和非線性對象進行了模擬研究。
