| 英文摘要 |
| We investigate the asymptotic stability problem of uncertain unified chaotic systems. Using sliding-mode
control theory, we develop a new method for designing the sliding-mode controller and its related control law for this type
of systems. This controller can make the movement starting from any point in the error space to enter the sliding mode in a
finite time and asymptotically reach the origin on the switching surface, thus, driving the uncertain unified chaotic system
to the equilibrium point. Compared with the existing controllers, the designed one exhibits many advantages, such as small
chattering, good stability and less conservative. The analysis of the motion equation and the simulation results demonstrate
that this method is effective. |
