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 ...

Coding techniques for fault-tolerant parallel prefix computations in Abelian groups
(2004)This paper presents coding techniques that can be used to provide fault tolerance to a parallel prefix computation that is performed on a binary tree of processing nodes. More specifically, we discuss how a parallel prefix ...

Encoded finite-state machines for non-concurrent error detection and identification
(2003)In this paper we develop a methodology for systematically constructing redundant finite-state machines in a way that enables an external mechanism to detect and identify transient state-transition faults by performing ...

Error detection and correction in switched linear controllers via periodic and non-concurrent checks
(2006)Control systems that utilize switched linear controllers have proven to be useful (and, in some cases, essential) for accomplishing certain control objectives in particular classes of plants. These controllers are often ...

Fault-tolerant computation in groups and semigroups: Applications to automata, dynamic systems and Petri nets
(2002)The traditional approach to fault-tolerant computation has been via modular hardware redundancy. Although universal and simple, modular redundancy is inherently expensive and inefficient. By exploiting particular structural ...

Fault-tolerant discrete-time linear time-invariant filters
(Institute of Electrical and Electronics Engineers Inc., 2000)Modular redundancy, the traditional approach to fault tolerance, is prohibitively expensive because of the overhead in replicating the hardware. In this paper we discuss alternative methods for obtaining fault-tolerant ...

Finite-State Machine Embeddings for Non-Concurrent Error Detection and Identification
(2003)In digital sequential systems that operate over several time steps, a state-transition fault at any time step during the operation of the system corrupts its state in a way that can render its future functionality useless. ...

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, ...

Nonconcurrent error detection and correction in fault-tolerant discrete-time LTI dynamic systems
(2003)This paper develops resource-efficient alternatives to modular redundancy for fault-tolerant discrete-time (DT) linear time-invariant (LTI) dynamic systems. The proposed method extends previous approaches that are based ...

Nonconcurrent Error Detection and Correction in Fault-Tolerant Linear Finite-State Machines
(2003)In this paper, we construct fault-tolerant linear finite-state machines (LFSMs) in which error detection and correction can be performed nonconcurrently (e.g., periodically). More specifically, by jointly choosing the state ...

Periodic and non-concurrent error detection and identification in one-hot encoded FSMs
(2004)State-transition faults in digital sequential systems, such as finite-state logic controllers, have traditionally been handled by embedding the given system into a larger one, in a way that preserves the state evolution ...

Position error signal estimation at high sampling rates using data and servo sector measurements
(2002)Track density in hard disk drives (HDD) is related to the performance characteristics of the HDD servo control system. Higher track density can be achieved by improving the performance characteristics of the servo controller ...

Surface failure detection for an F/A-18 aircraft using neural networks and fuzzy logic
(IEEE, 1994)In this paper we consider the problem of detecting control surface failures of a high performance aircraft. The detection model is developed using a linear, six degree of freedom dynamic model of an F/A-18 aircraft. The ...
