| Popis: | A new adaptive sliding mode controller is proposed for a second-order nonlinear dynamic system with the mismatch uncertainties. Firstly, a novel sliding surface with arctan function and the adaptive parameter is presented to be stable asymptotically of the system states on the sliding mode. Secondly, a nonlinear sliding mode controller is derived from the asymptotical stability of the closed-loop control system by Lyapunov method to eliminate the effect of the mismatch disturbances. Finally, an illustrative example is given to show that the sliding mode is more insensitive to the mismatched disturbances under the proposed adaptive sliding mode controller than those of two kind of sliding mode controllers. |
