Global adaptive output stabilization of uncertain nonlinear systems with polynomial output depending growth rate

This paper investigates the problem of global output stabilization for a family of uncertain nonlinear systems, which are dominated by a triangular-type condition. The distinguishing feature of such a class of systems is the presence of unmeasured states growth with growth rate polynomial of output-input multiplying an unknown constant. We show by an example that the power of the input in the growth rate seems to be optimal.Copyright © 2013 John Wiley & Sons, Ltd. Copyright © 2013 John Wiley & Sons, Ltd.
