Robust regulation of temperature in reactor-regenerator fluid catalytic cracking units. J. Alvarez-Ramirez, R. Aguilar and F. Lopez-Isunza. Ind. Engng. Chem. Res., May 1996, 35(5), 1652--1659.

An adaptive model-based control strategy is studied which makes use of calorimetric-state estimator techniques to obtain estimates of instantaneous rates of heat production due to chemical reaction. The estimates are included in input-output linearizing feedback controllers. The resulting controller is similar in form to standard input-output linearizing controllers and can be tuned analogously or by using a single gain parameter and is computationally efficient. 16 refs.
