Title: Lyapunov stability constrained adaptive nmpc for tubular bioreactors⋆
Authors: João Lemos xvii , José Igreja , Sérgio Costa
Abstract: An adaptive NMPC for a given class of uncertain (bio)systems with transport phenomena in which the manipulated variable is the velocity is formulated and developed. A stable distributed parameter estimator is derived, in the Lyapunov sense, and combined with the NMPC algorithm using the certainty equivalence principle. Stability, for the combined NMPC with the adaptive law, is guaranteed without increasing significatively the computational burden through a pointwise constraint that ensures outperforming a robust control stabilizing law. The design procedure and the resulting performance is illustrated by simulations in a bioreactor with a Contois kinetics.
