一种新的被控混沌系统抗干扰控制器设计方法

A New Disturbance Rejection Control Scheme for a Class of Controlled Dynamic Chaotic Systems

摘要:

针对一类动态混沌系统,在干扰幅值增大而影响被控混沌系统镇定的情况下,提出了一种利用补偿控制系统(敏感系统)抑制干扰幅值影响的控制设计方法. 这种方法首先将该敏感系统与原被控混沌闭环系统互联,然后通过设计敏感系统的自适应状态反馈控制器,以保证被控混沌闭环系统在干扰幅值增加的情况下仍能够渐近保持原有的稳定性；最后,通过仿真实例进一步验证了文章结论的有效性。

Abstract:

By employing the compensation system (sensitive system), the control scheme for disturbance amplitude rejection is proposed in this paper for a class of controlled dynamic chaotic systems in the case of disturbance amplitude increase. The control design first interconnects the controlled dynamic chaotic system with the sensitive system to form the interconnection system, then the adaptive state feedback controller is synthesized for the sensitive system to asymptotically guarantee the original stability of the controlled dynamic chaotic systems with disturbance amplitude increase. Finally, the demonstration of effectiveness is given in this paper by simulation example.
