Chapter 19 Programming the PID Algorithm - utoledo.edu

Ch 19 PID Block 1 Chapter 19 Programming the PID Algorithm Introduction The PID Algorithm is used to control an analog process having a single control point and a single feedback signal. The PID Algorithm controls the output to the control point so that a setpoint is achieved. The setpoint may be entered as a static variable or as a dynamic variable that is calculated from a mathematical operation. For many years, the PID Algorithm was not accepted as a function suitable for a PLC. It was included in a DCS (Distributed Control System) or configured from a number of stand-alone PID controllers. However, as PLC prices continued to fall during the 1980 s and later and more economical HMI systems were developed for the PLC, PLCs became more accepted as PID controllers. In fact, because PLCs have undercut the cost of competing systems, DCSs and other PID controllers have been forced to drop prices dramatically or no longer remain competitive.
