摘要
A robust fractional-order dynamic output feedback sliding mode control (DOF-SMC) technique is introduced in this paper for uncertain fractional-order nonlinear systems. The control law consists of two parts: a linear part and a nonlinear part. The former is generated by the fractional-order dynamics of the controller and the latter is related to the switching control component. The proposed DOF-SMC ensures the asymptotical stability of the fractional-order closed-loop system whilst it is guaranteed that the system states hit the switching manifold in finite time. Finally, numerical simulation results are presented to illustrate the effectiveness of the proposed method.
