摘　　要：通过对陈氏混沌系统施加非共振参数激励实现非反馈混沌控制.将远大于系统特征频率的周期信号作为控制输入,利用平均法和Lyapunov方法证明控制方案的可行性,并得出控制参数应满足的条件.数值研究表明此方法可以使受控系统迅速达到稳定状态,且具有较强的抗干扰性能.Nonfeedbaek chaos control of Chen＇s chaotic system is realized with nonresonant parametric drive. The control input is a periodic signal whose frequency is far higher than the system characteristic frequency. The feasibility of this scheme is proved by averaging method and Lyapunov method, and the condition of control parameter is obtained. Numerical researches show that the controlled system can reach stable state rapidly even when the control signal is noisy.
