A number of design variables is available in system identification to increase model accuracy in specified frequency bands: among others, one can resort to prefiltering or choose the sampling interval in a suitable way. In this paper a framework for

Data prefiltering is often used in linear system identification to increase model accuracy in a specified frequency band, as prefiltering is equivalent to a frequency weighting on the prediction error function. However, this interpretation applies on

This paper deals with the problem of optimal control of continuous-time autonomous linear switched systems on a finite control horizon. Sufficient conditions for optimality are developed using Hamilton-Jacobi-Bellman theory. The optimal switching sig

This paper deals with the problem of finding a lower bound for the optimal value of a quadratic cost functional for a continuous-time autonomous linear switched system. This bound is computed on the basis of a set of matrices that satisfies some mild

This work 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 ("switched equilibrium") which is not in the set of subsystems equilibria. Quadratic stability

This paper investigates the construction of a simulation model for the emission of nitrogen oxide (NO/sub x/) from a coal-fired power generation plant. A polynomial NARX model has been identified using a novel identification algorithm which includes

This paper investigates the problem of model structure selection for polynomial NARX models. In particular it discusses how classical identification approaches based on prediction error minimization may lead to an incorrect evaluation of the importan

A pruning mechanism is developed for the identification of polynomial NARX/NARMAX models. in order to systematically delete redundant terms inserted in the structure selection phase. The proposed approach is capable of overcoming somelimitations met

Classical prediction error approaches for the identification of non-linear polynomial NARX/NARMAX models often yield unsatisfactory results for long-range prediction or simulation purposes, mainly due to incorrect or redundant model structure selecti
