This PI-Controller is a Windows software Screen Object that operates as a self-contained, closed-loop, automatic process control system that can regulate temperature, pressure, flow rate, tank level, etc. It uses an input to read the data from a sensor, and an output for manipulating an actuator or control valve to keep the process variable at a specific set point. Two outputs can be used if a separate actuator is needed for positive and negative corrections. It features a bump-less transition from manual to automatic modes, a bump-less transition when changing the Integral gain, and an anti-windup offset bias for use when large errors or large changes in the set point occur.
