Action functional stochastic H∞ estimation for nonlinear discrete time systems
(2002)This paper presents an action functional, sample path optimization technique, for formulating and solving nonlinear discrete-time stochastic H∞ estimation problems. These H∞ problems are formulated as minimax dynamic games ...

Algebraic approaches for fault identification in discrete-event systems
(2005)In this note, we develop algebraic approaches for fault identification in discrete-event systems that are described by Petri nets. We consider faults in both Petri net transitions and places, and assume that system events ...

Coding approaches to fault tolerance in linear dynamic systems
(2005)This paper discusses fault tolerance in discrete-time dynamic systems, such as finite-state controllers or computer simulations, with focus on the use of coding techniques to efficiently provide fault tolerance to linear ...

Control of discrete-time partially-observed jump linear systems over causal communication systems
(2006)We consider the problem of control of discrete-time partially-observed jump linear system over a noisy causal communication channel. Necessary conditions for observability and stabilizability in probability and r-th mean ...

Discrete-time risk-sensitive filters with non-Gaussian initial conditions and their ergodic properties
(IEEE, 1999)In this paper, we study asymptotic stability properties of risk-sensitive filters with respect to their initial conditions. In particular, we consider a linear time-invariant systems with initial conditions that are not ...

Discrete-time stochastic minimax control of partially observable systems
(2001)This paper presents a sample path optimization technique, as an alternative to the ensample average in formulating and solving stochastic minimax dynamic games. The stochastic games are nonlinear, discrete-time, and partially ...

The evaluation of the Cultural Journeys in the Information Society environment as an educational aid
(2005)The Cultural Journeys in the Information Society is a dynamic hypermedia environment, which proposes the Electronic Roads as a meta-form for exploring cultural information that can form Cultural Journeys. The Electronic ...

Feedback control over packet dropping network links
(2007)This paper studies stabilization schemes for a discrete-time control systems in which the feedback loop includes a network link that may suffer packet drops. We model the packet dropping network link as an erasure channel ...

Feedback control utilizing packet dropping network links
(2002)The increasing availability of network connectivity has prompted the study of computer-based control methodologies that are implemented centrally or distributively using existing network infrastructure as the communications ...

Finite-time disturbance attenuation control problem for singularly perturbed discrete-time systems
(1998)In this paper we consider the problem of finite-time H∞-optimal control of linear, singularly perturbed, discrete-time systems. The problem is addressed from the game theoretic approach. This leads to a singularly perturbed, ...

H∞-optimal control of singularly perturbed discrete-time systems, and risk-sensitive control
(IEEE, 1994)The H∞-optimal control and risk-sensitive control of linear singularly perturbed, discrete-time systems is described. It is shown that the Riccati equation associated with the solution of the H∞-optimal control problem, ...

Maximum likelihood diagnosis in partially observable finite state machines
(2005)In this paper we develop a probabilistic approach for fault diagnosis in deterministic finite state machines (FSMs). The proposed approach determines whether the FSM under consideration is faulty or not by observing (part ...

Modeling and control design for a computer-controlled brake system
(1997)The brake subsystem is one of the most significant parts of a vehicle with respect to safety. A computer-controlled brake system has the capability of acting faster than the human driver during emergencies, and therefore ...

Multiple model adaptive mixing control: The discrete-time case
(2012)Most of the work in multiple model adaptive control with various forms of switching focused on continuous-time systems. The purpose of this technical note is to extend the results of one approach, the adaptive mixing control ...

Non-concurrent error detection and correction in discrete-time LTI dynamic systems
(2001)In this paper we develop fault-tolerant constructions for discrete-time (DT) linear time-invariant (LTI) dynamic systems that are build out of appropriately interconnected delay, adder and gain elements. More specifically, ...

Non-concurrent fault identification in discrete event systems using encoded Petri net states
(2002)In this paper we extend a previously developed coding-based methodology for monitoring faults in discrete event systems that are described by Petri nets. We present a systematic design that enables us to non-concurrently ...

Optimal stochastic control of discrete-time systems subject to total variation distance uncertainty
(2010)This paper presents another application of the results in [1], [2], where existence of the maximizing measure over the total variation distance constraint is established, while the maximizing pay-off is shown to be equivalent ...
