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 the PV sensor, and an output for manipulating the 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.
