| Abstract |
This work looks at how to robustly control fractional‑order nonlinear systems (FONS) that have unknown but bounded parameter uncertainties and external disturbances. We design an adaptive H∞ observer that estimates the states we cannot measure and also identifies the unknown parameters at the same time. Using these estimates, we create a fractional‑order sliding‑mode controller that ensures the closed‑loop system becomes asymptotically stable. Stability is proved with the fractional‑order Lyapunov criterion. To avoid the high‑frequency chattering that ordinary sliding‑mode control produces, we replace the discontinuous sign function with a fractional‑order power‑type continuous function in the switching law. This gives reliable state estimation and parameter identification while keeping the control signal smooth.
Numerical simulations test the observer‑based controller and show it can suppress external disturbances and cope with parameter changes in fractional‑order nonlinear dynamics. The framework provides a systematic way to analyze complex fractional‑order systems under severe uncertainties, achieving accurate tracking and strong disturbance rejection.
