In this paper, we study the robust consensus problem for a group of linear discrete-time agents to coordinate over an uncertain communication network, which is to achieve consensus against transmission errors and noises. We model the network by communication links subject to deterministic uncertainties, which can be either an additive perturbation described by some unknown transfer function or a norm...
Dynamic system modeling plays a crucial role in the development of techniques for stationary and non-stationary signal processing. Due to the inherent physical characteristics of systems usually under investigation, non-negativity is a desired constraint that can be imposed on the parameters to estimate. In this paper, we propose a general method for system identification under non-negativity constraints...
The stability problem of multiple additive time-delay system is considered using Lyapunov- Krasovskii stability theory. Based on the LMI (linear matrix inequality), the robust stability criterion and robust state-feedback controller design are derived for systems which may contain non-parameter uncertainties. Finally, a numerical example illustrates the validity and the lower conservation of the proposed...
