Like a concert grand piano, proportional-integral-derivative (PID) control algorithms need to be tuned to maintain a high level of performance.
Stability and optimization are the desired outcomes of PID control, which can exist in stand-alone controllers or as part of a large-scale system’s instruction set, as code is often used in conjunction with other control functions for more complex configurations.
Implementing and tuning a PID control system can be affected by upstream or downstream operations, as well as energy consumption, safety and regulations. In effect, PID control algorithms don’t exist in a vacuum.
ECS Solutions’ Rafael Zapata discusses the important factors to consider in this story from partner publication Automation World.
