Abstract

Generalized feedback linearization (GFL) is a control strategy aimed at extending input-output feedback linearization to certain nonstable invertible nonlinear systems. GFL maintains the distinctive simplicity of feedback linearization whilst overcoming the well known stable invertibility restriction of feedback linearizable systems. Preliminary results on the stability of the GFL strategy are presented. In particular, we show that the scheme is locally stabilizing for a broad class of nonlinear systems. Also, for the specific class of nonlinear systems of Lur´e type, we give sufficient conditions for the GFL scheme to be globally stabilizing
