MPC without terminal ingredients ensures stability and recursive feasibility in controlling the SEIR epidemic model.
Abstract
The article discusses a model predictive control (MPC) formulation tailored to the SEIR epidemic model without terminal conditions. It rigorously shows recursive feasibility and asymptotic stability of the disease-free equilibrium with a suitable prediction horizon. The paper highlights the importance of stability and recursive feasibility in MPC controllers applied to epidemics. Various numerical simulations demonstrate the impact of different weighting parameters on societal interventions and epidemic duration.
