We consider a Nehari problem for matrix-valued, positive-real functions, and characterize the class of (generically) minimal-degree solutions. Analytic interpolation problems (such as the one studied herein) for positive-real functions arise in time-series modeling and system identification. The degree of positive-real interpolants relates to the dimension of models and to the degree of matricial ... View full abstract»

In the field of computer security, a problem that received little attention so far is the enforcement of confidentiality properties by supervisory control. Given a critical system G that may leak confidential information, the problem consists in designing a controller C, possibly disabling occurrences of a fixed subset of events of G, so that the closed-loop system G/...

| | PDF (640 KB) | HTML

Research on numerical solution methods for partially observable Markov decision processes (POMDPs) has primarily focused on finite-state models, and these algorithms do not generally extend to continuous-state POMDPs, due to the infinite dimensionality of the belief space. In this paper, we develop a computationally viable and theoretically sound method for solving continuous-state POMDPs by effec... View full abstract»

In this paper, two reachability properties for single-input positive switched systems are introduced: monomial reachability and reachability. Monomial reachability, which represents a necessary but not sufficient condition for reachability, is fully characterized. Necessary and sufficient conditions for reachability are provided for the class of n-dimensional systems, switching among ... View full abstract»

Relay control is one of the simplest methods for stabilizing open-loop unstable processes by producing limit cycles. It is also used for parameter identification of unstable processes for the design of other types of controllers. In this paper, exact analysis of the limit cycles has been obtained for a class of high-order unstable SISO processes under relay control. A key technical lemma provides ... View full abstract»

This article proposes a new approach for computing a semi-explicit form of the solution to a class of Hamilton-Jacobi (HJ) partial differential equations (PDEs), using control techniques based on viability theory. We characterize the epigraph of the value function solving the HJ PDE as a capture basin of a target through an auxiliary dynamical system, called ¿¿characteristic system¿¿... View full abstract»

We propose a family of nonlinear state feedback global stabilizers for all planar linear systems which are globally stabilizable by bounded inputs (namely, all non exponentially unstable linear systems). This family is parametrized by a nonlinear function whose selection can yield quasi time-optimal responses, where the ??quasi?? is required to achieve local exponential stability of the closed loo...

Direct certainty equivalence results for output feedback stabilization of nonlinear systems are proposed. The first result is a simple extension of the indirect approach used in a paper by Praly and Arcak. The second result allows to deal with observers yielding nonuniformly converging estimates with respect to the norm of (a subset of) the system state. Application of these results ...

We analyze a call center with multiple customer types and dynamic priority service discipline, in which a low-priority customer becomes high priority when its waiting time exceeds a given deterministic service level threshold. Within each priority queue, the service discipline is first come, first served. Based on a fluid approximation of the system, we apply infinitesimal perturbation analysis (I... View full abstract»

This note considers output tracking of high-order stochastic nonlinear systems without imposing any restriction on the high-order and the drift and diffusion terms. By using the backstepping design technique, a smooth state-feedback controller is given to guarantee that the solution process is bounded in probability and the error signal between the output and the reference signal can be regulated ...

We consider the stability of the discrete-time networked control systems (NCSs) with polytopic uncertainty, where a smart controller is updated with the buffered sensor information at stochastic intervals and the amount of the buffered data received by the controller under the buffer capacity constraint is also random. We establish sufficient conditions for guaranteeing the exponential stability o... View full abstract»

This note presents an efficient distributed approach for computing a spatial average of parameters estimated by sensors in a wireless network. The most intuitive approach would rely on a two-step procedure. First, the nodes would estimate the local quantities, and second a distributed process would average these estimates over the network. Instead, the proposed algorithm combines both processes to... View full abstract»

This paper is concerned with the state estimation and sliding-mode control problems for continuous-time Markovian jump singular systems with unmeasured states. Firstly, a new necessary and sufficient condition is proposed in terms of strict linear matrix inequality (LMI), which guarantees the stochastic admissibility of the unforced Markovian jump singular system. Then, the sliding-mode control pr... View full abstract»

We consider the tracking problem of unknown, robustly stabilizable, multi-input multi-output (MIMO), affine in the control, nonlinear systems with guaranteed prescribed performance. By prescribed performance we mean that the tracking error converges to a predefined arbitrarily small residual set, with convergence rate no less than a prespecified value, exhibiting maximum overshoot as well as under...

In this article, we are concerned with the stabilization of a 1-D Schrodinger equation with boundary control and observation. The boundary observation is suffered from an arbitrary given time delay. We first show that the proportional output feedback control that stabilizes exponentially the time delay free system can not stabilize the corresponding time delay system anymore. We then use the obser... View full abstract»

• ### Stability of a Class of Hybrid Linear Stochastic Systems

The objective of the paper is to establish L q-stability results for the state processes of a new class of slowly time-varying hybrid continuous-time linear stochastic systems. The systems are hybrid in the sense that jumps both in the dynamics and the state may occur. In both cases a jump amounts to resetting to an initial value. Jump-times are defined by a more or less arbitrar... View full abstract»

• ### Avoiding Collisions in Flocks

Among the many models for flocking systems of interacting particles, the one introduced by Cucker and Smale has attracted attention due to the fact that a convergence to flocking (i.e., to a common velocity) could be established depending on conditions on the initial state of the system. In this note we extend this model by adding to it a repelling force between particles. We show that, for this m... View full abstract»

Quantized consensus assumes that the state of each node may only take nonnegative integer values. Reaching consensus under quantization is equivalent to determining a balanced assignment of identical tasks to nodes. In this note, we generalize this problem in two ways and denote the resulting framework discrete consensus. First, we consider tasks that are not identical: each one is characte...
