分析了一个具有扇区非线性输入且含有参数不确定性以及外部噪声干扰的主从混沌系统的同步控制问题.设计了一类同步滑模变结构控制器,并从理论上证明了该控制器的有效性.研究表明该控制器不受受控系统的参数变化和噪声干扰的影响,具有很强的鲁棒性.最后通过对主从Duffing_Holmes系统的仿真研究,验证了该控制器的有效性.
The synchronization control problem of a master-slave chaotic system with sector non-linear input and parameter uncertainty and external noise interference is analyzed. A class of synchronous sliding mode variable structure controller is designed and theoretically proved that the controller The research shows that the controller is robust to the changes of the controlled system parameters and the noise disturbance.At last, the simulation of the master-slave Duffing-Holmes system is performed to verify the effectiveness of the controller .
