摘要
在模糊滑模变结构控制基础上,研究具有不确定性Duffing混沌系统的同步控制问题。选择合适的滑模面,基于Lyapunov稳定性理论设计模糊滑模变结构控制器及自适应更新规则,从理论上证明控制系统的稳定性。由于控制器的设计是基于自适应模糊滑模变结构控制的,与常规方法相比,控制器滑动模态不受干扰的影响,有较好的鲁棒性和快速跟踪能力。通过数值仿真实验验证了该系统的有效性。
The synchronization of Duffing chaotic systems with uncertainty by sliding mode control is discussed. By choosing an appropriate sliding mode surface, a fuzzy-variable structure controller and adaptive update laws are designed to achieve synchronization based on the Lyapunov stability theory, and the stability of the control system is proved theoretically. This controller is based on adaptive fuzzy sliding mode. In contrast to custom methods, sliding ＂mode of this controller is free from the influence of disturbances, and the system has both better robustness and quick tracking. Synchronization simulations results show the effectiveness of the system.
