Enable AIC
Compensators Enables the Adaptive Inverse Control (AIC) compensation method for all
control channels that will support it. This box is available when the file has
been entered, a valid channel map exists, and at least one of the selected
channels supports AIC Compensation (which is done in Station Builder—see
the Edit Control Channels section for Station Builder in the MTS 793 Control
Software manual).
Note This compensation method will not optimize signals with frequency
content above 128Hz. Therefore, this process will not allow AIC to be
enabled if the sampling rate of the time histories exceed 256Hz.
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.
Status Displays messages about channel mapping and full-scale status after the
application checks the mapping and unit selections on the Mapping tab. These
messages are updated each time the user modifies the channel, mode, or unit
selection in the Mapping tab.
The application will ensure that no two file channels are mapped to the same
station channel. When the check is complete, the application will display either
“Invalid Channel Map” or “Valid Channel Map.” The process cannot be run
with an invalid channel map.
If the mapping is valid, the application checks full scales of each channel in the
file against the range of the selected control mode for each channel. The
message “Full Scales Outside Limits” or “Full Scales Inside Limits” will
display the results. If the mapping is bad, the outside limits text will display.
The valid/invalid channel map message and full scale in/outside limits
messages reflect the validity of the channel mapping and the comparison of
each file channel’s full scale versus the station channel’s full scale.
