通过在子结构中设定控制目标,通过引入大质量法在时域提出了子结构LQR控制算法。数值模拟在一大跨度的连体高层结构中进行,控制效果的对比表明,提出的子结构控制算法可以达到与传统控制算法相当的控制效果,同时相较传统算法,时域中的子结构LQR控制算法其需要的反馈信息传感器个数和控制方程维数都将大大减小,从而可以在很大程度上提高计算效率和实时控制效果。
By setting the control target in the substructure, the sub-structure LQR control algorithm is proposed in the time domain by introducing the mass method. The numerical simulation is carried out in a large-span Siamese high-rise structure. The comparison of the control effects shows that the proposed substructure control algorithm can achieve the same control effect as the traditional control algorithm. Compared with the traditional algorithm, the LQR The number of feedback information sensors and control equations required by the control algorithm will be greatly reduced, which can greatly improve the computational efficiency and real-time control effects.
