Abstract

Abstract Based on the T–S fuzzy model and the delayed feedback control (DFC) scheme, this Letter presents a robust synchronization strategy for a class of chaotic system with unknown parameters and disturbances. Being the response system, the designed robust observer can adaptively track the drive system globally. The T–S fuzzy model of the 4D chaotic system (Lorenz–Stenflo) is developed as an example for illustration. Numerical simulations are shown to verify the results.
