摘要:
研究了Lorenz-Haken(LH)振子处于混沌态时,注入余弦信号和δ脉冲对它的影响.通过数值计算了Lyapunov指数与余弦信号的无量纲振幅和无量纲调制频率及δ脉冲的周期和耦合常数的关系.结果表明:余弦信号无量纲振幅和δ脉冲的耦合常数的增加,将抑制混沌; 余弦信号无量纲频率和δ脉冲的周期的增加,将产生混沌.进而讨论了在不同条件下混沌态的演化和混沌控制的条件.
Abstract:
The influences of injected cosine signals and δ impulse array on the chaotic states of Lorenz-Haken oscillator are investigated. We demonstrate the relations between Lyapunov exponents and the dimensionless amplitude, the dimensionless modulation frequency of cosine signals, the period and the coupling constant of δ impulse array by numerical calculation. The numerical results show that the enhancements of the dimensionless amplitude of cosine signals and coupling constant of δ impulse arrays can inhibit the chaos, the enhancements of the dimensionless modulation frequency of cosine signals and the period of δ impulse can generate chaos. The evolutions and controls of the chaotic states are discussed.
