A Robust Nonlinear Observer for State Variables Estimation in Multi-Input Multi-Output Chemical Reactors

A Robust Nonlinear Observer for State Variables Estimation in Multi-Input Multi-Output Chemical Reactors

In this paper we tackle the on-line estimation of state variables in MIMO continuous stirred chemical reactor (CSTR) using a nonlinear observer. We prove the asymptotic stability of the resulting error system. Moreover, this observer has robust performance in the presence of model uncertainty and me...

description In this paper we tackle the on-line estimation of state variables in MIMO continuous stirred chemical reactor (CSTR) using a nonlinear observer. We prove the asymptotic stability of the resulting error system. Moreover, this observer has robust performance in the presence of model uncertainty and measurement noise. Finally, computer simulations are developed for showing the performance of the proposed nonlinear observer.
