摘要
在不同初始条件下,提出一种基于无源控制理论的控制方法,实现具有参数不确定性的两超混沌Chen系统的自适应同步.通过引入自适应控制,在线估计系统的参数,并设计一个自适应无源控制器,使两系统的同步误差方程转化为无源系统.根据无源系统理论,系统的动态误差方程将稳定于状态空间原点,即两超混沌Chen系统完全同步.仿真结果表明,所设计的控制器简单明了,控制方法有效.
Under different initial conditions,a control method based on passive control is proposed to achieve the adaptive synchronization of two hyperchaotic systems with uncertain parameters.The system parameters are estimated by introducing adaptive control,and an adaptive passive controller is designed to transfer the synchronization erroneous equation into a passive system.In terms of the passivity theory,the dynamic erroneous equation can be stable on the original point of the state space,namely,the two hyperchaotic systems can be completely synchronized.The simulation results have proven the simplicity and effectiveness of the designed controller.
