We study discrete breathers in prototypical nonlinear oscillator networks subjected to nonharmonic zero-mean periodic excitations. We show how the generation of stationary and moving discrete breathers are optimally controlled by solely varying the impulse transmitted by the periodic excitations, while keeping constant the excitation's amplitude and period. Our theoretical and numerical results show that the enhancer effect of increasing values of the excitation's impulse, in the sense of facilitating the generation of stationary and moving breathers, is due to a correlative increase of the breather's action and energy.
我们研究了受非谐零均值周期激励的典型非线性振荡器网络中的离散呼吸子。我们展示了如何仅通过改变周期激励传递的脉冲，同时保持激励的幅度和周期不变，来最优地控制静止和移动离散呼吸子的产生。我们的理论和数值结果表明，从促进静止和移动呼吸子产生的意义上讲，激励脉冲值增加的增强效应是由于呼吸子的作用和能量的相关增加。
