| 摘 要： | 应用驱动-响应同步方法,研究了一类二阶混沌系统的终端滑模控制.通过设计连续的终端滑模控制器实现混沌系统的有限时间同步.在控制器的设计过程中采用了一种改进的终端滑模面,有效克服了在常规终端滑模控制中由于参数选择不当而出现的奇异问题.仿真结果表明,改进的终端滑模控制器可有效降低变结构控制中所产生的抖振,并提高了系统的稳态精度,实现了混沌系统的有限时间同步.

| Abstract: | A terminal sliding mode controller of a class of second-order chaotic systems is studied on the basis of drive-response synchronization.The finite time synchronization of chaotic systems is realized by designing a continuous terminal sliding mode controller with an improved sliding surface introduced to get rid of the singularity phenomenon resulting from improper choice of parameter.Simulation results showed that the modified terminal sliding controller will not only reduce the chattering effectively but also improve the track ability and steady accuracy of the system,thus enabling the finite-time synchronization of chaotic systems to come true. |

| Keywords: | synchronization of chaotic systems terminal sliding mode control finite-time stability sliding surface chattering |
