Input-output decoupling of nonlinear recursive systems. (English) Zbl 1249.93037

Summary: The input-output decoupling problem is studied for a class of Recursive Nonlinear Systems (RNSs), i.e., for systems, modeled by higher order nonlinear difference equations, relating the input, the output and a finite number of their time shifts. The solution of the problem via regular static feedback known for discrete-time nonlinear systems in state space form, is extended to RNSs. Necessary and sufficient conditions for local solvability of the problem are proposed. This is the alternative to be used when some nonlinear input-output models cannot be realized in the state-space form.
