摘要
采用非线性反馈控制,用附加了带参数的正弦项对Chen系统进行了有效的控制。随着参数k的逐渐增大,系统的动力学行为呈现出一系列的变化。数值研究结果表明:随控制参数的增大,驱动信号的强度渐大,混沌系统由混沌运动到周期轨道,最终到一相点。
We use the method of nonlinear feedback control which added a sine terms with parameter to control the chen system effectively. Along with the augmentation of k, a series of variation takes play in the system's dynamical characteristics. Numerical simulation results show that the chaotic system varies from chaotic to periodic orbits, and to a phase point finally as the parameter k increasing.
