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 discretetime stochastic H∞ estimation problems. These H∞ problems are formulated as minimax dynamic games ...

Algebraic approaches for fault identification in discreteevent systems
(2005)In this note, we develop algebraic approaches for fault identification in discreteevent 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 discretetime dynamic systems, such as finitestate controllers or computer simulations, with focus on the use of coding techniques to efficiently provide fault tolerance to linear ...

Control of discretetime partiallyobserved jump linear systems over causal communication systems
(2006)We consider the problem of control of discretetime partiallyobserved jump linear system over a noisy causal communication channel. Necessary conditions for observability and stabilizability in probability and rth mean ...

Discretetime risksensitive filters with nonGaussian initial conditions and their ergodic properties
(IEEE, 1999)In this paper, we study asymptotic stability properties of risksensitive filters with respect to their initial conditions. In particular, we consider a linear timeinvariant systems with initial conditions that are not ...

Discretetime 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, discretetime, 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 metaform 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 discretetime 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 computerbased control methodologies that are implemented centrally or distributively using existing network infrastructure as the communications ...

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

H∞optimal control of singularly perturbed discretetime systems, and risksensitive control
(IEEE, 1994)The H∞optimal control and risksensitive control of linear singularly perturbed, discretetime 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 computercontrolled brake system
(1997)The brake subsystem is one of the most significant parts of a vehicle with respect to safety. A computercontrolled brake system has the capability of acting faster than the human driver during emergencies, and therefore ...

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