Time–delay systems are an important class of dynamical systems that provide a solid mathematical framework to deal with many application domains of interest. In this paper we focus on nonlinear control systems with unknown and time–varying delay signals and we propose one approach to the control design of such systems, which is based on the construction of symbolic models. Symbolic models are a...

This letter studies the consensus tracking control for multi-agent systems (MASs) of general linear dynamics considering heterogeneous constant known input and communication delays under a directed graph containing spanning tree. First, open-loop stable MASs, distributed predictive observer is proposed to estimate error construct that does not involve any integral term (which time-efficient in ...

Medline is a rich information source, from which links between genes and keywords describing biological processes, pathways, drugs, pathologies and diseases can be extracted. We developed a publicly available tool called CoPub that uses the information in the Medline database for the biological interpretation of microarray data. CoPub allows batch input of multiple human, mouse or rat genes and...

This paper investigates the distributed consensus tracking control problem for general linear multi-agent systems with external disturbances and heterogeneous time-varying input communication delays under a directed graph topology, containing spanning tree. First, all agents whose state matrix has no eigenvalues positive real parts, communication-delay-related observer, which is used to constru...

We formulate a linear program (LP) to simultaneously minimize the dynamic power and overall delay of a CMOS circuit. To eliminate all glitches either without or with minimal number of delay bu ers, a CMOS gate is assumed to have adjustable input to output delays for each input. Since these delays are not independent, a transistor sizing problem would require very complex non-linear optimization...
