Given a network of interconnected nodes, each with its own value (such as a measurement, position, vote, or other data), we develop a distributed strategy that enables some or all of the nodes to calculate any arbitrary function of the node values, despite the actions of malicious nodes in the network. Our scheme assumes a broadcast model of communication (where all nodes transmit the same value t... View full abstract»

• A Kinship Function Approach to Robust and Probabilistic Optimization Under Polynomial Uncertainty

In this paper, we study a class of robust design problems with polynomial dependence on the uncertainty. One of the main motivations for considering these problems comes from robust controller design, where one often encounters systems that depend polynomially on the uncertain parameters. This paper can be seen as integrated in the emerging area of probabilistic robustness, where a probabilistic r... View full abstract»

• Real-Time Suboptimal Model Predictive Control Using a Combination of Explicit MPC and Online Optimization

Publication Year: 2011, Page(s):1524 - 1534

| | PDF (568 KB) | HTML

Limits on the storage space or the computation time restrict the applicability of model predictive controllers (MPC) in many real problems. Currently available methods either compute the optimal controller online or derive an explicit control law. In this paper we introduce a new approach combining the two paradigms of explicit and online MPC to overcome their individual limitations. The algorithm... View full abstract»

The purpose of this paper is to study and design direct and indirect couplings for use in coherent feedback control of a class of linear quantum stochastic systems. A general physical model for a nominal linear quantum system coupled directly and indirectly to external systems is presented. Fundamental properties of stability, dissipation, passivity, and gain for this class of linear quantum model... View full abstract»

• On Codiagnosability and Coobservability With Dynamic Observations

Publication Year: 2011, Page(s):1551 - 1566
Cited by:  Papers (22)
| | PDF (982 KB) | HTML

Codiagnosability and coobservability in discrete event systems where observations are dynamic are considered. Instead of having a fixed set of observable events, the observation of an event is dynamic (trace-dependent) in this paper. A procedure is developed to transform the problem of coobservability to the problem of codiagnosability in the context of dynamic observations. This proves that probl... View full abstract»

• Robust Filtering Through Coherent Lower Previsions

Publication Year: 2011, Page(s):1567 - 1581
Cited by:  Papers (13)
| | PDF (587 KB) | HTML

The classical filtering problem is re-examined to take into account imprecision in the knowledge about the probabilistic relationships involved. Imprecision is modeled in this paper by closed convex sets of probabilities. We derive a solution of the state estimation problem under such a framework that is very general: it can deal with any closed convex set of probability distributions used to char...

• Stability Robustness in the Presence of Exponentially Unstable Isolated Equilibria

Publication Year: 2011, Page(s):1582 - 1592
Cited by:  Papers (9)
| | PDF (438 KB) | HTML

This note studies nonlinear systems evolving on manifolds with a finite number of asymptotically stable equilibria and a Lyapunov function which strictly decreases outside equilibrium points. If the linearizations at unstable equilibria have at least one positive eigenvalue, then almost global asymptotic stability turns out to be robust with respect to sufficiently small disturbances in the L...

We consider the ergodicity and consensus problem for a discrete-time linear dynamic model driven by random stochastic matrices, which is equivalent to studying these concepts for the product of such matrices. Our focus is on the model where the random matrices have independent but time-variant distribution. We introduce a new phenomenon, the infinite flow, and we study its fundamental properties a...

The n-step delayed sharing information structure is investigated. This information structure comprises of K controllers that share their information with a delay of n time steps. This information structure is a link between the classical information structure, where information is shared perfectly between the controllers, and a non-classical information structure, where there ...

| | PDF (661 KB) | HTML

An instance of a modular supervisory control problem involves a plant automaton, described either as a monolithic, finite-state automaton (SUP1M), or as the synchronous product of several finite-state automata (SUPMM), along with a set of finite state, specification automata on a common alphabet. The marked language of the synchronous product of these automata represents the desired specification.... View full abstract»

• Uniting Local and Global Output Feedback Controllers

Publication Year: 2011, Page(s):1636 - 1649
Cited by:  Papers (14)
| | PDF (626 KB) | HTML

We consider control systems for which we know two stabilizing output feedback controllers. One is globally asymptotically stabilizing, while the other one is only locally asymptotically stabilizing. We look for a composite output feedback control law that is equal to the local feedback on a neighborhood of the origin and that is globally asymptotically stabilizing. Since we want some robustness wi... View full abstract»

• Theory of Stochastic Dissipative Systems

Publication Year: 2011, Page(s):1650 - 1655
Cited by:  Papers (40)
| | PDF (243 KB) | HTML

By introducing the escape time, a new definition of the dissipativity is introduced under some assumptions that are very reasonable for most physical models. Based on this definition, criteria on the existence and the stability of the solution are presented, which can be seen as the extension of Lyapunov method to the non-smooth case. The dissipativity is applied to cascaded nonlinear stochastic s... View full abstract»

This technical note addresses the computation of the H∞ norm by directly computing the isolated common zeros of two bivariate polynomials, unlike the iteration algorithm that is currently used to find the H∞ norm. The proposed method to H∞ norm calculation is compared with the existing method [by Bruinsma and Steinbuch (1990)] using numerical e... View full abstract»

• Convergence and Equivalence Results for the Jensen's Inequality—Application to Time-Delay and Sampled-Data Systems

Publication Year: 2011, Page(s):1660 - 1665

| | PDF (394 KB) | HTML

The Jensen's inequality plays a crucial role in the analysis of time-delay and sampled-data systems. Its conservatism is studied through the use of the Grüss Inequality. It has been reported in the literature that fragmentation (or partitioning) schemes allow to empirically improve the results. We prove here that the Jensen's gap can be made arbitrarily small provided that the order of uni... View full abstract»

This note investigates dissipativity and related stability for discrete-time switched systems. The new concept of decomposable dissipativity is proposed for this kind of systems. By decomposing the supply rate into the main supply rate and the subsidiary supply rate, the “energy” changes of subsystems and “energy” dissipation in the whole switched system are explained. ...

In this technical note, we consider adaptive control of single input uncertain nonlinear systems in the presence of input saturation and unknown external disturbance. By using backstepping approaches, two new robust adaptive control algorithms are developed by introducing a well defined smooth function and using a Nussbaum function. The Nussbaum function is introduced to compensate for the nonline... View full abstract»

The first step in the diagnosis of failure occurrences in discrete event systems is the verification of the system diagnosability. Several works have addressed this problem using either diagnosers or verifiers for both centralized and decentralized architectures. In this technical note, we propose a new algorithm to verify decentralized diagnosability of discrete event systems. The proposed algori... View full abstract»

This technical note addresses the stability problem of delayed positive switched linear systems whose subsystems are all positive. Both discrete-time systems and continuous-time systems are studied. In our analysis, the delays in systems can be unbounded. Under certain conditions, several stability results are established by constructing a sequence of functions that are positive, monotonically dec... View full abstract»

In this technical note, we study the global disturbance rejection problem of nonlinear systems in lower triangular form with unknown exosystem via state feedback control. The problem is dealt with in two steps. In the first step, an augmented system composed of the given plant and an internal model is constructed. Owing to the presence of the unknown parameter in the exosystem, the augmented syste... View full abstract»

This article addresses the stability analysis of linear time invariant systems with aperiodic sampled-data control. Adopting a difference inclusion formalism, we show that necessary and sufficient stability conditions are given by the existence of discrete-time quasi-quadratic Lyapunov functions. A constructive method for computing such functions is provided from the approximation of the necessary... View full abstract»

We consider a class of convex Nash games where strategy sets are coupled across agents through a common constraint and payoff functions are linked via a scaled congestion cost metric. A solution to a related variational inequality problem provides a set of Nash equilibria characterized by common Lagrange multipliers for shared constraints. While this variational problem may be characterized by a n... View full abstract»

In this technical note an easy-to-use H∞/LTR control solution with mixed-sensitivity properties is presented. This theory can be viewed as an expansion of LQG control via H2 optimization point of view.
