摘要: Abstract This paper proposes a novel state feedback delay-range-dependent control approach for chaos synchronization in coupled nonlinear time-delay systems. The coupling between two systems is esteemed to be subject time-lags. Time-varying nature of both the intrinsic and delays incorporated broad scope present study better-quality controller synthesis. Lyapunov–Krasovskii (LK) functional employed derive conditions that can solved by means conventional linear matrix inequality (LMI)-tools. resultant master–slave considers non-zero lower bound as well time-delays. Further, delay-dependent condition has been established special case proposed LK treatment. Furthermore, condition, independent delay-rate, provided address situation when upper delay-derivative unknown. A robust methodology formulated chaotic networks against L 2 norm bounded perturbations minimizing gain from disturbance error. Numerical simulation results are show effectiveness methodologies.
