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 ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...

Everyone uses control loops. Anytime you adjust how you do something based on previous results, you are forming your own control loop. For example, when you want to drive your car at 65 mph, you ...
