摘要:
为了改善建筑结构控制效果,在模型不精确的前提下达到振动控制的目的.采用实际测量和预测相互结合的广义预测控制算法,通过引入相对稳定性矩阵和可调增益参数的办法来改进原控制算法,提高在地震作用时主动控制系统的稳定性.数值仿真表明:单纯附加相对稳定性矩阵来设计控制器虽然可以提高控制系统的稳定性,但控制效果不能保证,只有引入可调增益参数方可保证振动控制的效果; 可调增益参数应该根据实际控制的效果进行调整,而相对稳定性矩阵可根据原系统矩阵来选取,最好取对角矩阵; 其对角元素选取以改善原控制系统的极点分布为目的.
Abstract:
In order to ameliorate the control effect of building structures and achieve the objective of vibration control under the premise of imprecision model, a generalized predictive control algorithm, which combines actual measurement with prediction, is adopted. An improved control strategy is presented to increase the stability of active control system by introducing both relative stability matrix and adjusted gain parameter. Numerical simulation shows that the control effect can be assured only if the controller is designed with both relative stability matrix and adjusted gain parameter. The adjusted gain parameter can be determined by actual control effect, meanwhile, relative stability matrix can be acquired through original system matrix(better to choose diagonal matrix for convenience. The chosen diagonal elements should improve the poles distribution of original control system.
