The Almost Periodic Solutions

for a Class of Nonlinear Dynamical Systems

Abstract: The dynamic system itself has the very strong physics, the project and the vibration and so on actual background, but cycle Xie Hegai the cycle solution is also quite important in the practical application, has been one of non-linear dynamic system's important questions. This Wen Dui a kind of fourth-order misalignment dynamic system conducts the research, through constructs the Liapunov function, obtained generally the cyclical solution existence sufficient condition, on the one hand has solved generally the cyclical solution existence problem from mathematics itself, has promulgated this system hideaway essential characteristic, on the other hand, for physics, the project and the vibration and so on practical application raised has arched in the theory instruction function.

Key words: almost periodic solution；dynamical system；Liapunov function.
