We propose a scheme for choosing pseudo-leaders in a multi-agent group, which can be applied to an unconnected or switching neighbor graph. Expand

Synchronization-based topology identification of weighted general complex dynamical networks with time-varying coupling delay

Xiaoqun Wu
Mathematics
1 February 2008

Many existing papers investigated the geometric features, control and synchronization of complex dynamical networks provided with certain topology. However, the exact topology of a network is… Expand

Estimating the ultimate bound and positively invariant set for the Lorenz system and a unified chaotic system

Damei Li, J. Lu, Xiaoqun Wu, G. Chen
Mathematics
15 November 2006

To estimate the ultimate bound and positively invariant set for a dynamic system is an important but quite challenging task in general. In this paper, we attempt to investigate the ultimate bound and… Expand

Estimating the bounds for the Lorenz family of chaotic systems

Damei Li, Jun-An Lu, Xiaoqun Wu, G. Chen
Mathematics
2005

Abstract In this paper, we derive a sharper upper bound for the Lorenz system, for all the positive values of its parameters a, b and c. Comparing with the best result existing in the current… Expand

Sustained Slow-Scale Oscillation in Higher Order Current-Mode Controlled Converter
