This excerpt is from the Historical Perspective section. The proportional plus integral plus derivative (PID) control algorithm is the workhorse of virtually all closed-loop control applications. It ...

Machines and processes are controlled using many strategies, from simple ladder logic to custom algorithms for specialized process control, but proportional-integral-derivative (PID) is the most ...

Simple PI and PID control algorithms can provide precise control of first-order systems, and typical electronic motion controllers or even PLCs implementing simple P, PI, or PID algorithms can ...

Therefore, the response of a system controlled by PID terms alone slightly lags the target. If velocity and acceleration feed-forward control factors are added to the control algorithm ...

For example, when migrating from a PLC to a DCS, the PID tuning parameters are converted directly to the proper units and time bases for the algorithm choice. This maintains the established dynamic ...

PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...
