Resumen:
Recently, a Model Predictive Control (MPC) suitable for closed-loop re-identification wasproposed ([1]). This strategy try to solve the potential conflict between the persistent excitation of the system - necessary to perform a suitable identification - and the stabilizing control objectives. The main idea is to extend the concept of equilibrium-point-stability to the invariant-set-stability, and propose an MPC that: steers the system to that invariant set, when outside, and persistently excite the system, when inside. In this work, an application of this MPC to a nonlinear polymerization reactor simulator is made to explore the difficulties arising from the intention to approach real life problems. Several scenarios are simulated in order to clearly show the benefits and limitations of the proposed MPC strategy.
