本論文主旨在於探討具輸入飽和之系統，利用基因演算法為基礎的數位再設計，針對不同的輸入限制和不同的輸入訊號，可使輸入控制信號可以在輸入限制之下，得到最好的效能，並在不改變已存在系統架構的條件下，利用附加迴路來改善由於捲起效應所造成的非預期現象，並討論應用於非線性的混沌系統。在今日個人電腦的普及和數位晶片的發達與其良好的功能，如何從類比控制器轉換成數位控制器並儘可能保有原類比控制系統之性能亦是本論文主要的研究主題。

This thesis addresses some basic ideas for the systems analysis and synthesis with input saturation. By utilizing the digital redesign based genetic algorithm (GA), the control
systems can obtain well-performance for various input signals and constraints. The control object is to improve the performance without changing the existing structure. Then, the
scheme is experienced that tracking a periodic orbit within a chaotic system. With the rapid advances in computers and microprocessors, the important idea is to replace some existing
continuous controllers to associate with the digital implementation of digital signal processing chips.
