The tuning of proportional-integral-derivative (PID) control loops was an important change at HollyFrontier’s Navajo Refinery in Artesia, N.M. Its hands-on, “mandraulic” culture was no longer cutting ...

Proportional-integral-derivative (PID) control is one of the most common types of automatic control used in the power industry. A PID controller continuously ...

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 ...

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 ...

The two most common categories of process responses in industrial manufacturing processes are self-regulating and integrating. A self-regulating process response to a step input change is ...

Except, that is, “when you consider the aging workforce and the institutional knowledge of processes and instrumentation that has been slipping away.” Thus, advances in ...

There are two types of motion control engineers: Those who are comfortable tuning a servo loop, and those who aren't. The latter basically, have two options. The first is to use a non-servo device ...
