We consider the stabilization of a rotating temperature pulse traveling in a continuous
asymptotic model of many connected chemical reactors organized in a loop with continuously
switching the feed point synchronously with the motion of the pulse solution. We use the
switch velocity as control parameter and design it to follow the pulse: the switch
velocity is updated at every step on-line using the discrepancy between the temperature at
the front of the pulse and a set point. The resulting feedback controller, which can be
regarded 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.
