摘要
利用ＡＲ模型实时在线向前预测地震加速度，ＡＲ时间序列步长和控制时间步长可选取较优的比例关系．利用卡尔曼滤波作状态估计，对状态变量向前作一步最优预测．导出了适用于瞬时最优开环、闭环和开闭环时滞补偿控制算法理论公式．
Seismic excitations are expressed by using an AR model, excitation information is predicted forward in this paper. The better proportion is obtained between the AR sampling period and the control sampling period. The state vector is estimated using by Kalman filter equations. The state vector is predicted forward. The time delay compensationg control algorithm is derived which is suitable for instantaneous optimal Open Loop, Closed Loop and Closed Open Loop control.
