摘要:

针对一类受扰混沌系统的同步控制,采用具有扇区非线性输入的自适应滑膜变结构控制器,设计了相应的控制律和自适应律。在该控制器的作用下,实现了驱动系统和响应系统的同步控制,且不受扇区非线性输入、参数失配及外部干扰的影响,具有有很强的鲁棒性。所设计的控制策略简单,易于实现,而且没有强加在系统上的限制条件,因此应用范围较广。理论分析和数值仿真证明了该方法的有效性。

Abstract:

A method based on adaptive sliding mode variable structure controller with inputs sector nonlinearity is presented for synchronization of a class of chaotic system with perturbations. A control law and a adaptation mechanism are designed. The drive system and response system achieve synchronous control with this controller even if there exist inputs sector nonlinearity, perturbations and parameter mismatch.The controller is simple and easy to implement. Moreover, no restrictive assumption is imposed on the system.Thus, the applicability range of the proposed method becomes broad.Theoretical analysis and simulation results illustrate the validity.
