PID controller design has long been central to the stable and efficient operation of automatic voltage regulator (AVR) systems worldwide. Contemporary research in this field focuses on the ...

The process controller’s job is to maintain the process variable at setpoint, regardless of whether the setpoint is constant or has just been changed. The controller contains the “control algorithm,” ...

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

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 ...
