摘要
利用三维智能薄壳单元 ,研究了柔性薄壳智能结构的动态最优形状控制 ;提出了Riccati方程的分块迭代算法 ;给出了抛物面形天线的最优形状控制算例 .
The optimal shape control of flexible intelligent thin shell structure is derived by using the intelligent thin shell element presented. A new block iterative algorithm is presented by using the special feature of the continuous Riccati equation in the optimal shape control. Finally, a numerical example of a paraboloid antenna is given.
