Data pre-filtering is often used in linear identification to increase model accuracy in a specified frequency band, as pre-filtering is equivalent to a frequency weighting on the prediction error function. However, this interpretation applies only to a strictly linear setting of the identification problem. In this paper, the role of data and error(More)
— This paper deals with the problem of quadratic stabilization of switched affine systems, where the state of the switched system has to be driven to a point (the " switched equilibrium ") which is not in the set of subsystems equilibria. Quadratic stability of the switched equilibrium is assessed using a continuous Lyapunov function, having piecewise(More)

This paper investigates neural network based estimation of NO x emissions in a thermal power plant, fed with both oil and methane fuels. Two types of neural network namely a novel 'eng-genes' architecture and a Multilayer Perceptron (MLP) have been developed, both being optimised using genetic algorithms. Due to the local nature of the NO x generation(More)
