Abstract
The hepatitis B virus (HBV) has been interested by researchers to define control policy for the epidemic of this virus. In this study, the synergetic control approach was applied to determine the policy which consists of isolation, treatment, and vaccination for the epidemic system, including susceptible, acute infected, chronic infected and recovery individuals. The simulation was used to present the feasibility of the synergetic control approach in defining of all types of control inputs. It is clear from the simulation results that the hepatitis B epidemic system can be controlled based on the control policy including the isolation, treatment and vaccination provided by the synergetic control method. According to the results of this study, the control objective of the hepatitis B epidemic system can be achieved by using the synergetic controller. Additionally, the hepatitis B epidemic system could be controlled with the chattering free control inputs. Thus, it is suitable to utilize the synergetic approach for determination of control policy for the considered hepatitis B epidemic system. ฉ 2018 Association for Computing Machinery.
