Abstract
A closed loop feedback control system operates to maintain a process variable at or near a process variable setpoint. A digital filter is implemented with the controller to filter the process variable signal input to the controller. The filter includes both an amplitude filter to clip signal spikes and glitches and low pass filter to remove higher order, noise related frequencies from the signal, that could adversely affect computational speed of the controller.
