摘要: 研究了用非线性反馈控制混沌Lorenz系统的方法,经理论分析,给出了反馈控制函数的表达 式和混沌控制的期望结果,理论结果和数值结果一致表明,不同的控制函数可使系统稳定在不同的目标点或不同的周期轨道上.
Abstract: This paper investigates the methods for controlling chaos in the Lorenz system with nonlinear feedback functions. Feedback functions and results of controlling-chaos are presented through theoretical analysis. The results of theory and num erical calculations indicate that the trajectories of a chaotic system can be co ntrolled to approach the target periodic orbits or points by feedback functions.
