摘要
针对板结构形状的规则性 ,提出用有限条法进行建模 ,将二维薄板的控制设计降为一维控制问题的设计 .对模型进行模态分析 ,采用独立模态控制法 ,把原问题进一步降维 ,成为一系列标量微分方程的优化设计问题 .从而减少了振动主动控制设计的计算量和难度 。
According to the regularity of the plate structure, the finite stripe method is used for the modeling of the active vibration design, which transforms the 2 dimension problems to some 1 dimension ones. The modalities of the mode are analyzed. And the design dimension is reduced by using the independent modality space control method. The design is changed to a series of scalar quantity design problems, and the amount of calculation and the computational complexity are reduced. It is easy to compute the feedback quantity by using the linearity quadratic optimization method.
