Epidemiological Control of COVID-19 Through the Theory of Variable Structure and Sliding Mode Systems

This paper proposes a new mathematical model called SIRDQ considering control laws for the government actions in order to reduce quarantine periods. The proposed guarantee regulation of effective number reproduction desired value, which is directly related propagation epidemic model. We consider two strategies based on first-order sliding mode and super-twisting algorithm due its robustness with respect parametric uncertainties disturbances, as found epidemiological models. stability analysis closed-loop system rigorously presented. Simulations show that employed assure better levels isolation be adopted.
