Abstract
In this paper, start-up of a plate reactor is considered. Dynamic

optimization is used to obtain start-up trajectories, and a feedback

control structure for on-line control. The problem is challenging,

since the process model is large and highly non-linear. In

addition, the plant is subject to uncertainty. Special attention is

given to the problem of formulating an optimal control problem based

on physical insight. The robustness properties of the optimal solution

are explored in simulation, by introducing parameter perturbations into

the model. Automatic computer tools which greatly simplifies the task

of formulating complex dynamic optimization problems are... (More)
