| 英文摘要 |
| This paper investigates the event-triggered control for a class of uncertain nonlinear systems by proposing an
approximate solution input method. First, the nonlinear systems are linearized to the linear ones aiming to construct the approximate
solution. Second, according to the definition of the solution of the deterministic linear systems, we construct the
piecewise approximate solution for the uncertain nonlinear systems by utilizing the matrix parameters and sampled signals.
The measurement error is defined as the difference between the actual states and approximate states of the systems. Thereafter,
the event-triggered condition and controller are designed, respectively. The stability conditions are also developed
correspondingly. It is proved that the proposed method can effectively avoid the Zeno phenomenon. The proposed method
is also extended to the dynamic triggering method, and some improved results are developed. Finally, the effectiveness of
the proposed methods is verified by comparison examples. |
