| 摘 要： | 通过在线估计对象DARMA参数模型,引入一步超前最小预测方差控制,实现了对参考地震波的渐近无差跟踪.仿真结果表明,该方法控制精度较高,在线估计参数能迅速收敛,并具有良好的鲁棒性和抗干扰能力.该方法能一次性模拟地震波,克服了传统地震波形再现需要多次迭代的问题.

| Abstract: | The one-step-ahead minimal prediction error control method is introduced to earthquake waveform replication, which can estimate the parameter of DARMA model on line and track the reference earthquake wave without error asymptotic ally. The simulation results show that parameters estimation can be quickly convergent,and this method has high control accuracy, strong robustness and adaptive capacity for disturbing.This method do not need identify model of control object before forma test,which is a special advantage for earthquake waveform replication. |
