Abstract:

This thesis investigates stochastic optimal control problems with discrete delay and those with both discrete and exponential moving average delays, using the stochastic maximum principle, together with the methods of conjugate duality and dynamic programming. To obtain the stochastic maximum principle, we first extend the conjugate duality method presented in [2, 44] to study a stochastic convex (primal) problem with discrete delay. An expression for the corresponding dual problem, as well as the necessary and sufficient conditions for optimality of both problems, are derived. The novelty of

Abstract:

In recent years, the security of networked control systems (NCSs) has been an important challenge for many researchers. Although the security schemes for networked control systems have advanced in the past several years, there have been many acknowledged cyber attacks. As a result, this dissertation proposes the use of a novel time-delay switch (TDS) attack by introducing time delays into the dynamics of NCSs. Such an attack has devastating effects on NCSs if prevention techniques and countermeasures are not considered in the design of these systems. To overcome the stability issue caused by T

Abstract:

Le retard est un phénomène largement présent dans les systèmes de commande(i.e.retard physique, latence de communication, temps de calcul) et peut en dégrader les performances ou même les déstabiliser. Si le retard est faible, la stabilité en boucle fermée peut être garantie par des lois de commande conventionnelles mais ces techniques ne sont plus efﬁcaces si le retard est long. Cette thèse est dédiée à la commande des systèmes à retard avec retards longs inconnus ou avec des retards incertains. Pour compenser les retards longs, la commande prédictive est adoptée et des techniques d’estimatio

Abstract:

Questa tesi riguarda lo sviluppo di una nuova tecnica di controllo chiamata Delay Compensation per sistemi scalari che presentano un ritardo distribuito nei canali di ingresso. Lo scopo principale è di compensare realmente il lag intrinseco del sistema per un dato instante T_0. Esistono, infatti, alcune tecniche già utilizzate in questo ambito, chiamate predictor-like, che assegnano uno spettro stabile in closed-loop solamente dopo che il sistema è stato soggetto a tutto il ritardo presente in ingresso, non riuscendo perciò a compensarlo esattamente.

Abstract:

The main interest of the present thesis is the constrained control of time-delay system, more specifically taking into consideration the discretization problem (due to, for example, a communication network) and the presence of constraints in the system's trajectories and control inputs. The effects of data-sampling and modeling problem are studied in detail, where an uncertainty is added into the system due to additional effect of the discretization and delay. The delay variation with respect to the sampling instants is characterized by a polytopic supra-approximation of the discretization/del

Il existe différents scénarios dans lesquels on exige qu'un système fonctionne de manière périodique et, par conséquent, un besoin durable d'avoir un contrôleur capable de répondre à cette demande.

Néanmoins, si les systèmes considérés souffrent de retards temporels et/ou de types particuliers de signaux périodiques, les directives du paradigme du contrôle répétitif peuvent être trop strictes et tirées par les cheveux pour être suivies.

Abstract:

Timeliness in delivering packets for delay-sensitive applications is an important QoS (Quality of Service) measure in many systems, notably those that need to provide real-time performance. In such systems, if delay-sensitive traffic is delivered to the destination beyond the deadline, then the packets will be rendered useless and dropped after received at the destination. Bandwidth that is already scarce and shared between network nodes is wasted in relaying these expired packets. This thesis proposes that a deterministic per-hop delay can be achieved by using a dynamic queue threshold concep

Abstract:

This paper deals with the consensus problem under communication network inducing delays. It is well-known that introducing a delay leads in general to a reduction of the performance or to instability due to the fact that timedelay systems are infinite dimensional. For instance, the set of initial conditions of a time-delay system is not a vector but a function taken in an interval. Therefore, investigating the effect of time-delays in the consensus problem is an important issue. In the present paper, we assume that each agent receives instantaneously its own state information but receives the

The goal of the implemented algorithm is to maintain a certain Signal-to- Interference Ratio (SIR) for all users. Our analysis is done locally by linearizing the system around a steady state.

Abstract:

The signal propagation delays in a high speed, wide area telecommunication network can be orders of magnitude larger than a message transmission time. This implies that the response times associated with dynamic congestion management strategies can be long relative to the characteristic times of the queue-length processes being controlled, and that such strategies may be of limited use in controlling message loss in high speed settings. We examine the interplay between signal propagation delays and efficiency of feedback-based congestion controls in the case of a very simple network model cons
