采用优化GM(1,1)模型对结构实施灰色预测即时控制,推导结构状态向量的灰色预测方程,结合线性二次型最优控制理论(LQR),设计了结构的即时预测控制方案,并研究了不同地震波采样周期下其振动控制性能及时滞影响.分析结果表明,采用优化GM(1,1)模型进行预测控制有效减小了采样周期不同造成的始数据干扰误差,并且更有效地减小了结构振动控制的时滞影响.

The design procedures and application of the active optimal control to a building structure are proposed and studied based on the optimization GM(1,1) model and the modern control theories,Equations governing forecasted state vector of a building structure are derived and features of vibration control and influence of time delay based on different sampling period of seismic wave are analyzed.The study results show that the gray forecasting-optimal control based on the optimization GM(1,1) model is efficient to reduce the disturbance errors as different sampling period and influences of time-delay.
