✦ Synopsis

In this paper is studied the temperature regulation problem of a continuous stirred tank reactor with two consecutive and oscillatory exothermic reactions in which the heat of the reactions is unknown. A strategy to estimate the reactionsÏ heat from measurements of reactor temperature is proposed. This strategy is coupled with a linearizing-like feedback regulatory control. Practical convergence of this control scheme is proved when the uncertainty observer satisÐes the high gain assumption. The performance of the uncertainty observer and the closed loop behavior is illustrated by means of numerical simulations.

This paper deals with the state (chemical species concentration) estimation in stirred tank reactors when only reactor temperature is measured. The central idea is to construct a high-gain Luenberger observer based on a controller canonical form for nonlinear dynamics. It is shown that the observer
