本文提出了一种基于时延估计(TDE)和监督切换控制(SSC)的混沌系统控制与同步新技术。该方法由三个单元组成：消除系统动态的时延估计单元、形成误差动态的极点配置控制单元和当系统动态快速变化时被激活的SSC单元。利用李亚普诺夫分析方法证明了闭环系统的稳定性。为了验证该技术(TDE-SSC)的控制和同步性能，我们通过数值仿真将其与TDC进行了比较。结果表明，所提出的方案是一种易于理解、数值高效、稳健和精确的混沌系统控制与同步解决方案。
In this paper, we present a new technique, developed using time-delay estimation (TDE) and supervising switching control (SSC), for the control and synchronization of chaos systems. The proposed technique consists of three units: a time-delay estimation unit that cancels system dynamics, a pole placement control unit that shapes error dynamics, and an SSC unit that is activated when the system dynamics are rapidly changing. We prove the stability of the closed-loop system using the Lyapunov analysis method. To verify the control and synchronization performance of the proposed technique (TDE-SSC), we compare it with TDC using numerical simulation. Our results indicate that the proposed scheme is an easily understood, numerically efficient, robust, and accurate solution for the control and synchronization of chaos systems.
