Chaos Control and Global Stabilization of HIV Infection of CD+ 4 T-cells System
Year
: 2012
Abstract: In this paper a chaotic nonlinear system that called HIV infection CD+
4 T-cells is considered, and
a new approach in order to stabilizing the unstable equilibrium points of HIV infection CD+
4 T-cells system
with Lyapunov function stability theory, is introduced. The system appears exhibit a chaotic behavior for
some of the system parameters. The feedback control inputs for global stability in Lyapunov sense of this
system are obtained, as nonlinear function of the system densities. Numerical simulation results show that
the system trajectories can be globally asymptotically stabilized in the state space.
