Pannocchia, Gabriele and Bemporad, Alberto Combined design of disturbance model and observer for offset-free model predictive control. IEEE Transactions on Automatic Control, 52 (6). pp. 1048-1053. ISSN 0018-9286 (2007)Full text not available from this repository.
This note presents a method for the combined design of an integrating disturbance model and of the observer (for the augmented system) to be used in offset-free model predictive controllers. A dynamic observer is designed for the original (nonaugmented) system by solving an Hprop control problem aimed at minimizing the effect of unmeasured disturbances and plant/model mismatch on the output prediction error. It is shown that, when offset-free control is sought, the dynamic observer is equivalent to choosing an integrating disturbance model and an observer for the augmented system. An example of a chemical reactor shows the main features and benefits of the proposed method.
