| 英文摘要 |
| This paper studies the finite-time H∞ control problem for a class of stochastic nonlinear systems. Considering
the transient performance and anti-interference ability of the closed-loop system within a finite time interval, the Ito-type ?
stochastic nonlinear systems are studied. By constructing the Lyapunov function and linear matrix inequality (LMI), sufficient conditions for the system to satisfy the mean-square finite-time bounded are obtained. The finite-time H∞ controller
is further designed, and sufficient conditions for the system to satisfy both the mean-square finite-time bounded and the corresponding H∞ control performance are given. Finally, two examples are given to verify the feasibility and effectiveness of
the method. |
