| 摘 要： | 研究了一类具有匹配不确定性和外部扰动的统一混沌系统.通过对误差系统进行滑模变结构控制,实现了统一混沌系统的同步,并且利用滑模控制的特点,保证了同步系统的鲁棒性.当使用传统的趋近律方式的控制率时,系统往往会产生高频抖振,控制器在实际应用中得不到良好的效果.针对这一问题,利用高阶滑模的控制率,在保证系统鲁棒性的基础上,有效...

| Abstract: | The synchronization of two uncertain unified chaotic systems with external disturbance has been investigated by using sliding mode control.Because the chattering will be occurred by using traditional reaching law of sliding mode,high-order sliding mode control law is presented to eliminate the chattering phenomenon.The novel approach not only guaranteed the robustness of system,but also eliminated the chattering of error system.The simulations of Lorenz system and Chen system are given to demonstrate the fe... |
