Adaptive fuzzy anti-saturation sliding mode control for MIMO uncertain chaotic systems

This paper investigates the signal tracking problem of the uncertain multi-input-multi-output(MIMO) chaotic system with disturbance and input-saturation, and the fuzzy sliding mode anti-saturation control method with saturated nonlinear input is proposed. The designed controller can guarantee the system fast tracking the reference input, and the input signal fluctuation range is small. The method for the system's external disturbance has good robustness. Finally, taking the simulations on the unified chaotic system for example, the effectiveness of the proposed method is illustrated.
