- Abstract
This paper introduces a new backstepping-based sliding mode control strategy to realize the stabilization of a class of fractional-order system. The system is perturbed by unknown bounded unmodeled dynamics and external disturbances, meanwhile, the system parameters are unknown in advance. The effect of saturated input is considered to design the robust adaptive controller. For handling these unknown parameters, the proper sliding mode surface is constructed and some adaptive estimation laws can be assigned. The frequency distributed model is used so that the indirect Lyapunov theory is available in analyzing the stability of every subsystem. Finally, simulation results are presented to verify the effectiveness and feasibility of the proposed control strategy.
