About the Extended Adaptive Inverse Control (AICX) Compensator
In addition to the AIC compensator, MTS also offers the AICX compensator.
The AICX compensator offers greater processor efficiency than AIC, which makes it a better choice for some
applications, such as systems with higher channel counts. Also, the AICX compensator is typically used with
systems that are equipped with Series 494 Hardware.
However, for systems that currently achieve adequate compensation with AIC, there may no advantage to
switching to AICX.
When you turn on AIC in the Station Builder application, both the AIC and AICX compensators will be available
when you open the station configuration file with the Station Manager application.

Description Item
Sets how quickly compensation values are applied to
converge the feedback and command signals. Forward/Inverse Convergence Rate
Sets a time delay between the desired and response
signals. Anticipation
Sets the length of the adaptive filter, which affects the
lowest frequency dynamics of the Impulse Response
controller/actuator/specimen combination being
compensated. Longer times compensate lower
frequencies, but slows adaptation.
Important:
The use of the AICX compensator can
introduce large delays between generated
command and command to the actuator. The
delay is dependant on the tuning of AICX and
is two times the value of the Impulse Response.
Sets the range in which AICX operates. Frequencies
outside this range are not compensated. Operating Band
Hold—Continues to use current values but stops
adapting new values. Adaptation State
Resume—Adapts and continuously updates
compensation values.
Clears acquired compensation values and restarts
the adaptation process. Reset Fwd
