A control system includes a measurement device capable of gathering high
frequency process parameter data, a modeling routine which uses the high
frequency parameter data to develop a model of the high frequency noise
and a compensation routine that employs the developed model to adjust a
control signal to thereby compensate for the high frequency noise present
within the process parameter. The measurement device may measure a
process variable at a relatively high frequency and send a subset of the
measured data (e.g., the low frequency data) to a standard controller
that generates a control signal to control the measured process parameter
in any known manner. The modeling routine analyzes the high frequency
data and develops a mathematical model of the high frequency noise within
the process variable. The resulting mathematical model may then be used
by the compensation routine to alter the standard control signal produced
by the controller before that control signal is delivered to or used by
the device being controlled.
