摘　　要：针对混沌非线性系统的同步化问题 ,给出了一个较为一般的模型 ;我们利用混沌吸引子的特有性质 (如混沌吸引子有界性等 ) ,对于所给模型 ,采用滑动模控制律实现了混沌同步化 ;在误差可观测的条件下 ,设计了观测器 。In this paper,the problem of robust (adaptive) synchronization of chaotic nonlinear systems with a unified model is considered.Two main methods are proposed in different cases.Sliding mode control is used when the states of the two synchronized systems can be measured,though the considered systems may contain uncertain parts.Adaptive control with an observer is employed when only output information about the systems is known,where sliding mode control is also adopted to improve the robustness of the adaptive control systems.
