| 摘 要： | 将磁流变阻尼器引入到轻型TLP的垂向半主动控制中.使用水动力软件AQWA求取轻型TLP频域内的一阶力、二阶力等水动力参数,通过MATLAB语言编写程序,选取线性二次型经典最优控制（LQR）算法和限界Hrovat半主动最优控制算法,通过对安装了磁流变阻尼器的TLP的垂向半主动控制进行数值模拟,并与采用LQR算法的主动控制以及无控状态进行对比,表明其具有良好的减振效果.

| Abstract: | The magneto-theological damper was applied to the vertical semi-active control of the light TLP. The hydrody- namic software AQWA was used to calculate the first and second order force as weU as the hydrodynamic parameters of the plat- forms in the frequency domain. With the MATLAB program, the hnear quadratic classic optimal control （LQR） algorithm and threshold Hrovat optimal control of semi-active algorithm were selected for numerical simulation of the vertical semi-active control of the TLP installed with magneto-rheological damper. Comparing with active control using LQR algorithm as well as free state showed that it has good damping effect. |
