Robust Exponential Converge Controller Design for a Unified Chaotic System with Structured Uncertainties via LMI

الملخص EN

This paper focuses on the chaos control problem of the unified chaotic systems with structured uncertainties.

Applying Schur-complement and some matrix manipulation techniques, the controlled uncertain unified chaotic system is then transformed into the linear matrix inequality (LMI) form.

Based on Lyapunov stability theory and linear matrix inequality (LMI) formulation, a simple linear feedback control law is obtained to enforce the prespecified exponential decay dynamics of the uncertain unified chaotic system.

Numerical results validate the effectiveness of the proposed robust control scheme.
