摘要

通过在线估计液压振动台及试件预测器DARMA模型与参数，引入预测方差目标最优函数，实现对目标振动位移信号的实时渐近无差跟踪。通过系统仿真及联台试验，其控制结果表明，该方法控制精度高，在线估计参数能迅速收敛，并具有良好的鲁棒性和削弱噪声能力，能够直接跟踪目标振动位移一次性完成振动试验。该方法有别于传统的振动控制技术，不需要辨识传递函数及预实验，可直接实现高精度振动模拟。

Abstract

The one-step-ahead minimal prediction error control method used to tracking the vibration displacement wave on line was achieved by estimating the parameter and DARMA model of hydraulic shaking table with introducing optimum function of predict variance target. The simulation and experimentation results show that parameters estimation in this way can be quickly convergent with high control accuracy, strong robustness and adaptive capacity for disturbing. This method achieved following the vibration in displacement directly. Compared to traditional control mode, it is a special advantage for highly accuracy vibration simulation in time-domain without identifying control object and multi-iterations before format test.
