Adaptive mixing control with multiple estimators
(2012)A recently proposed adaptive control scheme with mixing involves the use of precalculated candidate controllers whose output is weighted on the basis of the parameter estimates generated by an online parameter estimator. ...

Designs of bisimilar Petri net controllers with fault tolerance capabilities
(2008)This paper proposes an approach for providing tolerance against faults that may compromise the functionality of a given controller modeled by a Petri net. The method is based on embedding the given Petri net controller ...

Directly computable L2 and L∞ performance bounds for morse's dynamic certainty equivalence adaptive controller
(1995)In this paper we consider a model reference adaptive control scheme where the classical error augmentation and standard tuning error normalization are avoided through the use of Morse's high‐order tuner. We consider the ...

Article
Dynamical neural networks that ensure exponential identification error convergence
(1997)Classical adaptive and robust adaptive schemes, are unable to ensure convergence of the identification error to zero, in the case of modeling errors. Therefore, the usage of such schemes to 'blackbox' identification of ...

Evaluation of likelihoodratio and performance bounds for nonlinear decision problems via stochastic PDE
(American Automatic Control Council, 1994)The nonlinear binary decision problem with signal satisfying a diffusion equation observed through noisy measurements is considered. Using the unnormalized conditional density of nonlinear filtering, expressions for ...

Faulttolerant linear finite state machines
(Institute of Electrical and Electronics Engineers Inc., 1999)In this paper we develop a framework for constructing faulttolerant dynamic systems, focusing primarily on linear finite state machines (LFSMs). Modular redundancy, the traditional approach to fault tolerance, is expensive ...

Heteroskedastic linear regression: Steps towards adaptivity, efficiency, and robustness
(Springer New York LLC, 2014)In linear regression with heteroscedastic errors, the Generalized Least Squares (GLS) estimator is optimal, i.e., it is the Best Linear Unbiased Estimator (BLUE). The Ordinary Least Squares (OLS) estimator is suboptimal ...

Hidden markov model classification based on empirical frequencies of observed symbols
(IFAC Secretariat, 2014)Given a sequence of observations, classification among two known hidden Markov models (HMMs) can be accomplished with a classifier that minimizes the probability of error (i.e., the probability of misclassification) by ...

Article
Measuring the impact of adversarial errors on packet scheduling strategies
(2013)In this paper we explore the problem of achieving efficient packet transmission over unreliable links with worst case occurrence of errors. In such a setup, even an omniscient offline scheduling strategy cannot achieve ...

Article
A meshless numerical identification of a soundhard obstacle
(2012)We propose a simple meshless method for detecting a rigid (soundhard) scatterer embedded in a host acoustic homogeneous medium from scant measurements of the scattered near field. This inverse problem is illposed since ...

Multichannel deconvolution with long range dependence: Upper bounds on the Lprisk (1 ≤ p < ∞)
(2015)We consider multichannel deconvolution in a periodic setting with longmemory errors under three different scenarios for the convolution operators, i.e., supersmooth, regularsmooth and boxcar convolutions. We investigate ...

A new robust adaptive control scheme for linear time varying plants
(2002)In a recent work, a new linear adaptive controller based on certaintyequivalence and backstepping design, which promises a level of transient and asymptotic performance comparable to that of the tuning functions adaptive ...

Nonlinear control design for linear time varying systems
(1996)A new class of linear controllers for linear time varying systems are proposed. These controllers are based on nonlinear tools such as integrator backstepping and nonlinear damping, and on a new filter structure that ...

Article
Performance analysis for a changepoint problem
(1999)Nonlinear stochastic differential equations are used to model a version of the changepoint problem. State estimates of the minimum meansquareerrortype are used in likelihoodratio tests to detect the time of change. ...

Article
Robustness of nonlinear control systems with respect to unmodeled dynamics
(1999)In theory, it can be established that nonlinear control laws for linear or nonlinear plants can be used to meet strict performance requirements. The success of these control designs in practical situations will very much ...

Teachers' Attitudes Towards Their Pupils' Mathematical Errors
(2000)This article is mainly concerned with the didactical and the epistemological approach towards pupils' errors in mathematics. The findings of an investigation into a representative sample of Cypriot teachers' attitudes of ...
