Signal filtering in PID control
Abstract
The major input signals entering the PID controller
are: the setpoint, the process output, and measurable load
disturbances. By feeding these signals through suitable
filters before they enter the PID controller, the
properties of the feedback loop can be improved
significantly. This presentation will treat setpoint
handling, feedforward from load disturbances, TITO
control, noise filtering, and process dynamics
compensation.
