In this article, theoretical and the experimental studies are reported on the adaptive control of vibration transmission in a
strut system subjected to a longitudinal pulse train excitation. In the control scheme, a magneto-strictive actuator is
employed at the downstream transmission point in the secondary path. The actuator dynamics is taken into account.
The system boundary parameters are first estimated off-line, and later employed to simulate the system dynamics. A
Delayed-X Filtered-E spectral algorithm is proposed and implemented in real time. The underlying mechanics based
filter construction allows for the time varying system dynamics to be taken into account. This work should be of interest
for active control of vibration and noise transmission in helicopter gearbox support struts and other systems.
