| Popis: | 103 Based on the Lyapunov stability theorem, a sliding mode observer is proposed in this thesis for a class of single-input-two-output uncertain nonlinear systems with mismatched disturbances. A sliding surface function is firstly designed for the proposed observer with adaptive mechanisms embedded, so that the upper bounds of perturbations are not required to be known in advance, and the first state estimation error is able to reach zero within a finite time. Secondly stability analysis is demonstrated to ensure that the rest of state estimation errors have the ability to achieve asymptotic stability. A numerical example and a practical example are illustrated for showing the feasibility of the proposed methodology. |
