| 摘 要： | 由结构动力系统的微分方程建立起了动力系统控制的数学模型, 然后基于计算结构力学与最优控制的模拟关系, 用结构力学中的子结构消元法求解了Riccati方程, 从而确定了动力系统的最优控制律。数值例题说明了文中方法的有效性。

| Abstract: | A control mathematical model of the dynamic system is established according to the differential equation obtained from the structural dynamic system.Mixed energy of time interval is defined and condensation formulas are given with the help of the variational principle.Further the substructural condensation method in structural mechanics is used for the Riccati equation solution,based on the simulation relation between computational structural mechanics and optimal control.Then,the optimal control of the dynamic system is obtained.The numerical example shows the effectiveness of this method. |
