This article presents an extension of existing set-valued integrators for nonlinear parametric ODEs to enable sensitivity analysis. The main focus is on continuous-time set-valued integration, and a derivation of auxiliary ODEs describing high-order inclusions of the adjoint trajectories, together with their terminal and transition conditions, is presented based on polynomial model arithmetics. A numerical implementation for the adjoint set-propagation based on SUNDIALS-CVODES is discussed, and this new sensitivity bounding capability is illustrated with two case studies in batch processing and dynamic parameter estimation.

Abstract
This article presents an extension of existing set-valued integrators for nonlinear parametric ODEs to enable sensitivity analysis. The main focus is on continuous-time set-valued integration, and a derivation of auxiliary ODEs describing high-order inclusions of the adjoint trajectories, together with their terminal and transition conditions, is presented based on polynomial model arithmetics. A numerical implementation for the adjoint set-propagation based on SUNDIALS-CVODES is discussed, and this new sensitivity bounding capability is illustrated with two case studies in batch processing and dynamic parameter estimation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
