Adaptive observers for a class of multi-output non-linear systems. (English) Zbl 0769.93016

Summary: Sufficient differential geometric conditions are given for the existence of global adaptive observers for a class of multi-output nonlinear systems which are linear with respect to a vector of unknown constant parameters. They extend to multi-output systems earlier results on adaptive observers for single-output systems; they also extend to systems with unknown parameters results obtained previously on the existence of non-adaptive observers with linear error dynamics.
