ROBUST FEEDBACK STABILIZATION OF CHEMICAL REACTORS

This paper deals with the temperature stabilization of a large class o f continuously stirred tank chemical reactors, We design state feedbac k controllers, and we show their ability to globally stabilize the tem perature at an arbitrary set point in spite of uncertainties on the ki netics, Furthermore, it is also shown that these controllers can handl e input constraints along the closed-loop trajectories in some instanc es, For the implementation purpose, we design a robust state observer for the case of partial state measurement, and we prove that its incor poration in the feedback loops does not impair the nominal stabilizati on properties of the controllers.
