Extensions of sliding-mode adaptive observer are presented for state reconstruct nonlinear systems with uncertainty having unknown bounds. The observer uses non gains that are smoothened versions of classical sliding-mode gains and they are co ously updated to guarantee a globally stable observation error. This observer is ap to Chua’s circuit in a chaotic synchronization scheme. A generalization to known w form type disturbances and measurement uncertainties is pointed out. @S0022-0434 ~00!02304-2#
