Title Of Article :
Robust control with uncertainty estimation for feedback linearizable systems: application to control of distillation columns
Latin Abstract :
The goal of this paper is to describe a linearizing feedback adaptive control structure which leads to a high quality regulation of
the output error in the presence of uncertainties and external disturbances. The controller consists of three elements: a nominal
input±output linearizing compensator, a state observer and an uncertainty estimator, which provides the adaptive part of the con-
trol structure. In this way, the feedback controller, based on the disturbance observer, compensates for external disturbances and
plant uncertainties. The eectiveness of the controller is demonstrated on a distillation column via numerical simulations.
