Sliding mode observer is governed by control that compensates a so-called Ito's term, which reflects a stochastic nature of a system. The matrix estimation algorithm based on equivalent control are proposed. A numerical example illustrates the effectiveness of the proposed approach

By varying the support composition different nickel speciation on the calcined precursors was evidenced. The main role of TiO2 appeared to be two-fold: (a) inhibition of the formation of hardly

The suggested estimation algorithm is based on the least squares method (LSM) with forgetting factor. The forming filter generating this ‘coloured‘ noise from a standard ‘white noise’ is assumed to be partially known. An analysis of the convergence zone is presented. A numerical example illustrates the effectiveness of the proposed algorithm.
