一类 E13系统极限环的定性分析
Qualitative Analysis of Limit Cycles of a E13 System
摘要
Abstract
The paper investigates the existence and uniqueness of limit cycle of E 13 system.By introducing Liapunov series and transformation of Poincaréto discuss the type of its limited singular point and infinite point .Then the sufficient conditions for non-existence of limit cycle are given by using three common methods.Meantime,by applying Hopf bifurcation theory and Poincare-Bendixson’s ring domain theorem,we generalize the sufficient conditions for the existence and uniqueness of limit cycle.关键词
