Nonlinear adaptive control of COVID-19 with media campaigns and treatment.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the infection of severe acute respiratory syndrome coronavirus 2, which is spreading all over the world and causing huge human and economic losses. For these reasons, we study the adaptive control problem of COVID-19 in consideration of media campaigns and treatment in this paper. Firstly, a novel compartment model is constructed by analysing the spread mechanism of COVID-19 and a nonlinear adaptive control problem is established. Then, using the estimation of parameters updated by adaptive laws, the controllers are designed to achieve the control goals. Finally, numerical examples are presented to illustrate the control capability to the outbreak of COVID-19. • A COVID-19 model with media campaigns and treatment is established. • The adaptive control problem of COVID-19 model is proposed. • The controllers are designed by using estimated parameters to reach control goals. • The phenomenon of secondary or even multiple outbreaks of COVID-19 is shown.
