摘要
针对一类状态不能全部测量且含有不确定因素的混沌系统的同步问题,设计了一个带有控制器的非线性观测器.当系统的非线性项满足一定条件时,不论系统是处于平衡点、周期、拟周期、混沌或超混沌状态,都可使观测器的状态按照目标系统给定的轨道演化,并且是大范围内可同步的.计算机仿真结果表明了所提出方法的有效性.
This paper investigates the synchronization design for a class of chaotic systems with uncertainties in which all state variables are not measured. The design makes use of an observer with a controller. Assuming the boundedness of chaotic attractors and limited cycles, the approach, which is both global and not relying on complete knowledge of the systems involved, is rigorously proved by means of Lyapunov theory. Computer simulation results illustrate the validity of the method.
