摘　　要：利用信号处理中的互相关技术可以对声发射波之间的时间延迟进行测量的功能,实现对变化的时滞参数的跟踪,并将其同模糊控制以及Smith预估控制相结合,形成了一种基于时滞辨识的模糊Smith控制算法,对此算法进行仿真研究。仿真结果证明了此算法的有效性。Tracking of varying time delay is realized by using the cross - correlation technology of signal processing, which can take measure of the time delay between acoustic em/ssion waves. Then a fuzzy Smith control algorithm based on time delay identification is formed by combining it with fuzzy control and Smith predictive control. Simulations are made and the results show that the approach is effective.

关 键 词：时滞辨识 模糊控制 SMITH预估控制
