About Compensators
Compensators compare the command with the corresponding sensor feedback to ensure that the command
is fully applied to the specimen. If the sensor feedback indicates the specimen is not reaching the commanded
levels, the compensator alters the command until the desired result is achieved.
For example, suppose the program source is a sine wave that calls for a ±10 cm displacement, and the LVDT
feedback only achieves ±9 cm. A peak/valley compensator monitors the feedback and automatically boosts
the initial command to ensure that the LVDT feedback reaches the ±10 cm command. You can view the
compensated command with the Station Manager application’s scope and meters.
