Abstract :
The problem of representing a class of nonlinear systems by both left and right BIBO (bounded-input-bounded-output) coprime factors is studied. Based on the coprime factorizations, the class of all stabilizing controllers of a particular structure for the set of plants under consideration is then characterized in terms of a BIBO stable map, Q. The results specialize to the Youla-Kucera parameterization in the linear case. Results giving the various conditions for a nonlinear feedback system to be well-posed are also presented
