【Abstract】 A novel adaptive fuzzy control method is proposed via backstepping approach for a class of chaotic systems with unknown nonlinear terms or external disturbances. The fuzzy approximator whose parameters can be self-tuned in real-time mode is applied to estimate the unknown terms in the system model. Given initial parameters, the controller can be derived iteratively according to the control law and update laws to make the system asymptotically trace any desired orbit. The illustrative examples demonstrate the effectiveness of the proposed method.更多还原
