| 摘 要： | 利用滑动模态控制的思想讨论一类不确定统一混沌系统的混合同步问题.采用指数滑模到达条件设计混合同步控制器,借助极点配置原理设计切换函数,顺利实现带有非线性项的滑动模态混合同步.与以往方法相比,文中给出的控制器可使滑动模态不受干扰影响,系统有快速的跟踪能力和很好的鲁棒性,切换函数参数的确定更为方便,所得结果保守性小.

| Abstract: | Hybrid synchronization of the unified chaotic system with disturbance is investigated.Using the principle of poles assignment method,the switching function is designed to guarantee Anti-synchronization of slide mode with nonlinearity terms.Using modified exponent hitting condition of sliding mode,a robust synchronization controller is proposed.In contrast to the previous works,sliding mode of this controller is free from the influence of disturbance,and the system has both better robustness and quick tracking.Therefore the computation is simple and the conservation is smaller. |
