Adaptive backstepping fuzzy synchronization control of fractional-order chaotic systems with input saturation and external disturbances

In this paper, an adaptive backstepping command filtered controller is proposed for a class of uncertain strict feedback fractional-order chaotic systems with input saturation and external disturbances. A filter designed to avoid the “explosion complexity” problem in conventional technique. To tackle error improve synchronization accuracy, compensation mechanism provided. Meanwhile, fuzzy logic are utilized approximate unknown functions, disturbance observers constructed reduce impact particular, chattering phenomenon, smooth function rather than sign used design, stability closed-loop system can be guaranteed by controller. simulation study provided confirm practicality validity method.
