中文摘要：
采用调谐质量阻尼器（Tuned Mass Damper,TMD）设计了铰接塔海洋平台的振动主动控制方法。首先给出了考虑重力梯度、水压力差、波浪力等外部载荷作用的系统动力学方程,并采用有限差分法对方程进行了离散,而后采用最优控制方法设计TMD的主动控制,并给出了TMD参数的设计方法。仿真结果表明,主动TMD的控制效果优于被动TMD,而且主动控制时的TMD位移量明显小于被动控制方法。
英文摘要：
A tuned mass damper （TMD） was designed in the vibration control for an articulated tower plat- form. The motion equation of the system was firstly given with considering gravity, water pressure difference and wave force, and this equation was discreted using the finite difference method, Then active controller was designed using the optimal control method. The determination of parameters of TMD was also given in this paper. Simulation results indicate that the control effectiveness using active TMD control is better than that using passive TMD control, and the displacement of the TMD using active TMD control is smaller than that using passive TMD control.
