| 摘 要： | 研究了多输入时滞反馈控制作用下斜拉梁主共振问题.采用多尺度法,推导了位移时滞和速度时滞反馈控制作用下斜拉梁非线性主共振的解析解,分析了主共振响应随参数变化的规律,控制参数时滞和控制增益对系统非线性主共振响应的影响.结果表明:合理地调整时滞值、控制增益可以提高振动控制的效率,拓宽减振频率范围,且在参数的调节中时滞较控制增益对减振更为有效.

| Abstract: | The primary resonance responses of cable-stayed beam under multi-input time-delay feedback control were studied. Using the multi-scale method, the analytical solution of the nonlinear primary resonance of the cable-stayed beam under multi-input time-delay feedback control was derived. The results show that reasonable adjustment of time delay value and control gain can improve the efficiency of vibration control and widen the frequency range of vibration reduction. And adjusting the time delay is more effective than the control gain for damping vibration.#$NLKeywordscable-stayed beam, vibration control, multi-time delay, primary resonance |
