This paper is concerned with the H 2 and H∞ control problems in networked control framework, dealing specifically with cases where the communication between the components is made via a multi-hop network susceptible to packet loss, which is modeled by a Markov chain with Bernoulli distribution. The aim is to investigate the trade-off between the network resource saving and the closed-loop performance degradation in the context of state-feedback control. The performance of the control design is measured by means of the H 2 and H∞ norms. Two main topics are evaluated: i) The influence of the initial probability distribution on the design of the controller; and ii) The relationship between the expected value of the output signal energy and the probability of successful transmissions (associated with the maximum allowable transmission per data packet) for a given transport scheme and a given performance criterion. The results are applied in a case study based on a linearized numerical model of the Furuta's inverted pendulum.

Food webs over time: evaluating structural differences and variability of degree distributions in food webs López, Daniela N.; Camus, Patricio A.; Valdivia, Nelson; Estay, Sergio A. (2018-12)Ecological networks are usually analyzed as time‐aggregated units, where time‐specific interactions are aggregated into one single network. However, the extent to which the structure of these time‐aggregated networks ...
Optimal multiculture network design for maximizing resilience in the face of multiple correlated failures Prieto, Yasmany; Boettcher, Nicolas; Elena Restrepo, Silvia; Pezoa, Jorge E. (2019-05)Current data networks are highly homogeneous because of management, economic, and interoperability reasons. This technological homogeneity introduces shared risks, where correlated failures may entirely disrupt the network ...
