Abstract:
A chaotic system has complex dynamical behaviors, such as depending sensitivity on tiny variation of initial conditions, having bounded trajectories in the phase space. For this reason, it is often necessary to design control mechanism that will force a system to exhibit a dynamics, even when intrinsically chaotic. It is important to control and eliminate chaos in the attitude satellite system. This paper is devoted to study the problem of controlling chaos in chaotic satellite system. This paper proposed a fuzzy sliding mod controller method for the stability to chaotic satellite. on the other hand, The aim of this article is to use the fuzzy sliding mode control technique based on the Lyapunov stability theory to study the control behavior of the attitude chaotic satellite. The proposed controller ensures that, attitude satellite system to move the point of unstable equilibrium. The simulation results indicate that the proposed control scheme can suppress the chaos of satellite system, and track the reference signal successfully even under the uncertainty.
