The servo controller for seismic simulation shaking table is usually made up of three-parameter feedback, feed forward links and signal generator. By deducing the transfer function for each feedback and feed forward link the values of three parameters for the servo controller can be tuned efficiently.

Beneath the table are mechanical devices called actuators that work together to simulate an earthquake. Typically, two actuators shake the table along the X axis, two shake the table along the Y axis, and four shake the tables vertically along the Z axis. The tables can also rotate independently along each of these three axes.
