题目:Synchronization of coupled harmonic oscillators with delayed positions


报告人:宋强(副教授河南工业大学)


摘要:In this talk, we address the synchronization problem for a network of coupled harmonic oscillators by proposing a distributed control algorithm by only utilizing position states, i.e. outdated position states stored in the memory. The coupling strength of the network is conveniently designed based on the absolute values and the principal arguments of the nonzero eigenvalues of the network Laplacian matrix. By analyzing a finite number of stability switches of the network with respect to the variation of the time delay, some necessary and sufficient conditions are derived for reaching synchronization in networked harmonic oscillators with positive and negative coupling strengths, respectively, and it is shown that the time delay should be taken from a set of intervals bounded by some critical values. Simulation examples are given to illustrate the effectiveness of the theoretical analysis.
