Abstract
For bistable time-delay dynamical systems modeling the dynamics of viral infections and the virusinduced immune response, an efficient approach is proposed for constructing optimal disturbances of steady states with a high viral load that transfer the system to a state with a low viral load. Functions approximating the behavior of drugs within the framework of well-known pharmacokinetic models are used as basis functions. Optimal disturbances are sought in the W21 norm. It is shown that optimal disturbances found in this norm are superior to those found in the L2 norm as applied to the development of adequate therapeutic strategies.
