结构主动控制系统时间滞后测量与补偿方法

Methods for measuring and compensating time delay of active structural control system

本文研究了结构主动控制系统时间滞后产生的原因，利用作者建立的结构主动控制系统进行了系统时间滞后测量方法的研究，测量得到了该系统时间滞后的具体数值。在此基础上，研究了时间滞后对控制系统的影响。提出了结构主动控制系统时间滞后的三种补偿方法，即移相法、泰勒级数展开法和预估状态向量法。通过主动控制试验验证了时间滞后补偿方法的有效性。

In this paper, the cause for time delay of the active structural control system and methods for measurement of system's time delay by using authors' active structural control system are studied. The data of time delay are got. Accordingly, effects of the time delay on control system are studied. Three methods for compensating time delay, i. e. phase compensation, Taylor series expansion, predictive vector are given, which are proved to be valid by experiments.
