Abstract

We consider the stabilization of a rotating temperature pulse traveling in a continuousasymptotic model of many connected chemical reactors organized in a loop with continuouslyswitching the feed point synchronously with the motion of the pulse solution. We use theswitch velocity as control parameter and design it to follow the pulse: the switchvelocity is updated at every step on-line using the discrepancy between the temperature atthe front of the pulse and a set point. The resulting feedback controller, which can beregarded as a dynamic sampled-data controller, is designed using root-locus technique.Convergence conditions of the control law are obtained in terms of the zero structure(finite zeros, infinite zeros) of the related lumped model.
