On the Role of Constraints in Optimization under Uncertainty

This thesis addresses the problem of industrial real-time process optimization that suffers from the presence of uncertainty. Since a process model is typically used to compute the optimal operating conditions, both plant-model mismatch and process disturb ...

How Important is the Detection of Changes in Active Constraints in Real-Time Optimization?

Dominique Bonvin, Saurabh Anand Deshpande

In real-time optimization, enforcing the constraints that need to be active is important for optimality. In fact, it has been established in the context of parametric variations that, if these constraints are not satisfied, the optimality loss would be O($ ...

Selective Input Adaptation in Parametric Optimal Control Problems with Path Constraints

Dominique Bonvin, Benoît Chachuat, Saurabh Anand Deshpande

This paper is concerned with input adaptation in dynamic processes in order to guarantee feasible and optimal operation despite the presence of uncertainty. For optimal control problems having mixed control-state constraints, two sets of directions can be ...

Parametric Sensitivity of Path-Constrained Optimal Control: Towards Selective Input Adaptation

Dominique Bonvin, Benoît Chachuat, Saurabh Anand Deshpande

In the context of dynamic optimization, plant variations necessitate adaptation of the input profiles in order to guarantee both feasible and optimal operation. For those problems having path constraints, two sets of directions can be distinguished in the ...
