- •
In this study, a new fractional-order sliding mode controller based on disturbance observer is designed.
- •
The finite time stability and mismatched disturbance rejection for a class of fractional-order nonlinear systems is investigated.
- •
The finite time and robust stability of closed loop systems is proved via fractional calculus and Lyapunov stability theory.
- •
Simulation results with some comparisons demonstrate the effectiveness of the proposed method.
