Resumen:
The optimal feedback control of nonlinear chemical processes, specially
for regulationand and set-point changing, is attacked in this paper.
A novel procedure based on the Hamiltonian equations associated to a
bilinear approximation of the dynamics and a quadratic cost is
presented. The usual boundary-value situation for the coupled
state-costate system is transformed into an initial-value problem
through the solution of a generalized algebraic Riccati equation.
This allows to integrate the Hamiltonian equations on-line, and to
construct the feedback law by using the costate solution trajectory.
Results are shown applied to a classical nonlinear chemical reactor
model, and compared against standard MPC and previous versions of
bilinear-quadratic strategies based on power series expansions.
