Abstract
In this paper we present an approach suitable for optimal constrained
control of processes subject to uncertainties. The controller follows from a nominal
solution of dynamic optimisation of a theoretical model which needs not to be very
accurate. The nominal optimal control trajectory is identified as a sequence of arcs
and boundaries. Real output measurements are used to cancel model mismatch
and to augment nominal inputs on-line using state-feedback law. Neighbouringextremal
controller is designed to follow the nominal output trajectory in interior arcs
using necessary conditions for optimality (NCO). Methodology will be implemented
for setpoint-transition of van de Vusse reactor type. Finally, the performance of
neighbouring-extremal controller will be benchmarked using several perturbation
scenarios.
