摘要
针对一类参数不确定的统一混沌系统,提出一种脉冲控制方法.该方法采用系统状态变量的线性反馈作为脉冲控制信号,来实现统一混沌系统的全局渐近稳定,同时给出了统一混沌系统新的全局渐近稳定判据,并对其进行了扩展,与现有的研究结果相比,降低了全局渐近稳定条件的保守性.该方法所设计的控制器结构简单,易于实现,且响应速度快,可为保密通信与混沌载波信号扩展谱等应用提供坚实的理论基础,理论分析和仿真结果验证了方法的有效性.
An impulsive control scheme for a class of unified chaotic systems with parameter uncertainty is proposed using the linear state feedback as the signal to realize the global asymptotic stability, In addition, some new global asymptotic criteria and their extended forms are presented, Compared with the existing results, less conservative conditions are obtained to guarantee the global asymptotic stability. The controller thus designed is simple and easy to implement at high response speed and available to lay down a theoretical foundation for the applications in chaotic secure communication systems and chaotic spread spectrum of carrier communications. The effectiveness of the method proposed is verified theoretically and simulatively.
