Highlights A new topic (COVID-19 epidemic) has been introduced in the literature of control theory. A new robust control algorithm has been applied to the COVID-19 nonlinear system after making some assumptions. The data of the paper are valid for a certain period of time and the controller could be applied to the same system with different data. The stability of the system has been achieved using Lyapunov stability analysis and the system performance has been improved much better. The parameters of the proposed controller have been optimized using new optimization method called the Most Valuable Player Algorithm (MVPA). The MVPA has introduced for the first time to the literature of control theory.
