有参数失配的非自治混沌系统同步的间歇控制

Synchronization of Nonautonomous Chaotic Systems with Parameter Mismatch via Intermittent Control

采用正弦状态误差反馈的间歇控制,来研究n维有参数失配的非自治混沌系统的同步问题.所考虑的参数失配存在于系统的外激励中,通过李雅普诺夫稳定性理论和圆盘定理推导出了一些同步准则,并对相应的同步误差进行了分析.最后,数值仿真验证了控制策略的有效性.

Synchronization of n-dimensional nonautonomous chaotic systems with parameter mismatch via intermittent control of sinusoidal state error feedback was investigated. The parameter mismatch exists in the external excitation of the system. Some synchronization criteria are deduced by the Lyapunov stability theory and the Gerschgorin disc theorem, and the corresponding synchronization error bound is analytically estimated. Subsequently, numerical simulations demonstrate the effectiveness of the control strategy.
