在振动最优控制中，由于目标函数不一定由状态变量描述，因此振动的控制特性取决于建模中的准则函数和坐标系。在这项研究中，控制特性和准则函数之间的关系进行了研究的两种情况下，忽略动态的干扰和限制的频率范围内的干扰，由于缺乏知识的动态干扰的前馈控制的最优控制。通过数值计算，阐明了前馈控制可以通过限制扰动频率范围来优化目标函数，而选择绝对速度作为目标函数，可以获得与天棚阻尼器相同的控制效果。
In optimal vibration control, the control characteristics of vibration depend on the criterion function and the coordinate system in the modelling, since the objective function is not necessarily described by the state variables. In this study, the relationships between the control characteristics and the criterion functions were investigated for the two cases of ignoring the dynamics of disturbance and restricting the frequency range of disturbance in the optimal control with the feedforward control due to lack of knowledge of the dynamics of disturbance. By carrying out numerical calculations, it was clarified that the optimization of the objective function can be given by feedforward control restricting the frequency range of disturbance, and that the same control effectiveness as the sky-hook damper can be obtained by choosing the absolute velocity as the objective function.
