Abstract
The feedback passivity problem in nonlinear discrete-time systems is examinedin this paper. The characteristics of the relative degree and zero dynamics of the non-passive system are related to its feedback passivity property. The main contribution is the study of the relative degree properties of single-input single-output (SISO) passive systems in general form, and the use of them in the proposal of sufficient conditions to render this class of systems passive by means of a static state feedback control law. Some notes, based on previous results, referring the feedback passivity problem of multiple-input multiple-output (MIMO) nonlinear systems which are affine in the input are also given.
