针对核电站管道系统中动力阻尼器的设计问题，提出了一种基于线性矩阵不等式（LMI）的优化设计方法，该方法考虑了弹性构件的疲劳寿命和阻尼因子难以调整或预先确定等实际约束条件。在这种情况下，经典的不动点理论不再适用。因此，我们应用基于线性矩阵不等式的控制理论来求解动力阻尼器的最优设计参数。作为一个说明性的例子，我们设计了一个简支动力阻尼器，并通过数值模拟和振动台试验显示其性能。
We present a Linear Matrix Inequality (LMI) based optimal design scheme for a dynamic damper to be installed in piping systems in nuclear power plants, taking account of some practical constraints including the fatigue life of the elastic members and damping factor which is hard to adjust or pre-fixed. In such a usual situation, the classical fixed-point theory is not applicable. Therefore, we apply the LMI-based control theory to solve the optimal design parameters of the dynamic damper. As an illustrative example, we design a simply supported dynamic damper and show its performance by numerical simulation and shaking table tests.
