摘要


此論文的主要目的是用畫系統響應曲線的方法來探討非線性系統之特 性。為了這個目的 ,有關的方法先作了簡短的複習,然後用來分析幾種 非線性系統。此論文之貢獻在於對三階 非線性系統首次畫出一個RAS (region of asymptotic stability) 的邊界曲線,以及顯示 出利亞譜 諾夫曲面在三度空間中與系統響應曲線的關係。.

並列摘要


The main purpose of this thesis is to study nonlinear system characteristics by plotting the trajectories with a computer. In order to do this, the methods used in this thesis are reviewed briefly. The contributions of this thesis are that some of the three dimensional boundaries of RAS (region of asymptotic stability) are first obtained in this research work, and that for a third order system the relations between the Lyapunov function and the system trajectories can be realized.
