DESIGN OF ADAPTIVE LINEARIZING CONTROLLERS FOR NONISOTHERMAL REACTORS

This paper deals with the control of the temperature in non-isothermal stirred-tank reactors involving M (M greater-than-or-equal-to 1) chem ical reactions. The proposed control algorithm is an input-output line arization controller which accounts for the well-known process nonline arities. The control scheme is also adaptive in order to deal with the parameter uncertainty: in particular it is shown how to include expli cit on-line estimates of the M activation energies within the adaptive linearizing controller. The performance of the control law is illustr ated in simulation.
