Stabilization with interpolated controllers: application to the tracking control of a continuous stirred tank reactor

We obtain results that establish sufficient conditions for simultaneous stabilization using interpolated controllers for plants with variable operating conditions, under nonlinear perturbations in their parameters. These results generalize previous results for interpolated controllers. Based on these results we present an application to tracking closed-loop control of a continuous stirred tank reactor, where a single exothermic reaction takes place. A comparison with simple PI controllers is made.
