Chapter 2 deals with the fundamental theory and methods of bifurcation. the conditions giving rise to the static bifurcation are derived at first, then, the improved ls reduction method is studied and the centre manifold method is simplified
第二章研究分岔的基本理論和方法,推導了一般一維非線性微分動力系統發生鞍?結分岔、叉式分岔和跨臨界分岔等基本靜態分岔的條件,改進和簡化了高維非線性微分動力系統的降維方法。Primary resonance saddle - node bifurcation control of forced duffing system
振動系統的主共振鞍結分岔控制The author puts forward the thought of analyzing bifurcation and chaos in dc / dc converters with the theories of nonlinear dynamics, and the thought of controlling nonlinear problems with linear controlling methods of modern control theory. chapter three ( research on bifurcation and chaos in pwm dc / dc converters ) first theoretically analyzes and emulates period - doubling bifurcation of pwm dc / dc converters with the " inverse " piecewise numerical emulation. then the author analyzes in detail the sampled - data model, the mathematical model, which is suitable to the nonlinear research of dc / dc converters
第三章( pwm型dc dc變換器中分岔與混沌的研究)首先採用「逆向」分段數值模擬法對pwm型dc dc變換器中的倍周期分岔進行了理論分析與數值模擬;接著詳細地分析了適合於dc dc變換器非線性研究的數學模型一采樣數據模型,提出了dc dc變換器中存在環面分岔與鞍結分岔的可能性;最後通過電路實驗驗證了在電路參數發生變化時, dc dc變換器經歷一系列的倍周期分岔通向混沌的演化過程,並對混沌態下dc dc變換器的輸出特性進行了分析與小結。
