PFC Design Realizing Output Feedback Exponential Passivity for Exponentially Stable Non-Linear Systems

Ikuro Mizumoto, Shinya Ohishi, Zenta Iwai
This paper deals with a design problem of a parallel feedforward compensator (PFC) which realizes the output feedback exponential passive (OFEP) system. One can easily design an adaptive output feedback control system for such nonlinear systems satisfying the OFEP conditions. We propose a design scheme of a PFC for making a non-OFEP nonlinear system OFEP. The nonlinear system considered here is exponentially stable but not restrict to minimum phase.
