悬臂梁基础固支端水平方向受到振动强度RMS值为1g的高斯随机激励，有效激振频带为200Hz。要求设计合适的振动控制方案，使得在控制器的作用下，该悬臂梁自由端的随机振动响应具有良好的抑制效果。-Gaussian basis cantilever clamped horizontally by the end of the vibration intensity 1g RMS value of random excitation, the effective excitation band of 200Hz. To design a suitable vibration control scheme, making the role of the controller, random vibration response of the free end of the cantilever has a good inhibitory effect.
