Vibration Controllers "close the loop" on Vibration Test
Systems. LDS-Dactron is the market leader, both by worldwide sales
volume and by technology sophistication.
With two distinct hardware platforms (COMET and LASER), and two levels of
software (the Engineering-oriented Premier level and the more basic, production-oriented
Value level), LDS-Dactron can offer a variety of products at
different price-points to meet your budget & technical objectives.
Both controllers offer these great features:

A Vibration Controller receives vibration signals
from accelerometer(s) attached to the Shaker/Vibrator and compares the measured accelerations to
the desired accelerations defined by the test specification profile. Real-time adjustments are made
to the output signal, which is fed to the Amplifier driving the Vibrator. This iterative process maintains the
fidelity of the table vibrations throughout the test, regardless of system non-linearities, temperature
changes, system drift, DUT resonances, etc.
