Application of Model predictive control suitable for closed loop re-identification to a polymerization reactor

Recently, a Model Predictive Control(MPC) suitable for closed-loop re-identification wasproposed ([1]). This strategy try to solve the potentialconflict between the persistent excitation of the sys-tem - necessary to perform a suitable identification -and the stabilizing control objectives. The main idea isto extend the concept of equilibrium-point-stability tothe 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 thiswork, an application of this MPC to a nonlinear poly-merization reactor simulator is made to explore thedifficulties arising from the intention to approach reallife problems. Several scenarios are simulated in or-der to clearly show the benefits and limitations of theproposed MPC strategy.
