This paper is motivated by a class of positive systems with an input that subject to unknown state-dependent power law delay as well saturation. For example, biological networks have non-negative protein concentration states. Mass action kinetics in these result behavior, while complex interactions cause signal propagation delays. Incomplete network characterization makes state-dependence unkno...

In this paper, we consider the global consensus problem for discrete-time multi-agent systems with input saturation constraints under fixed undirected topologies. We first give necessary conditions for achieving global consensus via a distributed protocol based on relative state measurements of the agent itself and its neighboring agents. We then focus on two special cases, where the agent mode...

Fault-tolerant constrained attitude controllers are proposed for flexible spacecraft in the presence of input saturation and actuator fault, as well as model uncertainty and external disturbance. Two input saturations, that is amplitude saturation and, amplitude and rate saturation are considered and simple and effective compensators are designed to deal with the effect of input saturation. Two...
