Abstract

A nonlinear output feedback control strategy for chemical reactor models which are affine in the unmeasured state variables is proposed. The nonlinear controller design is based on input-output linearization. Online estimates of the state variables are provided by a nonlinear closed-loop observer with guaranteed stability properties. Simulation results for a simple chemical reactor model demonstrate the superior estimation and control performance that can be obtained with the proposed technique as compared to input-output linearization based on a linear observer
