For example, if a feedwater flow control loop oscillates because its set point is oscillating, the problem lies with the drum level controller. The fault analysis should then be applied to the ...

For example, an oscillating reheat steam temperature control loop can cause oscillations in the generator load, throttle pressure, fuel, and drum level controllers.

A better understanding of closed-loop control, and how to tune it, can be found by looking at the individual parts of the PID equation and the effect of each on the controlled output By Bill Dehner ...

Many loop problems can be solved readily by tuning, and testing for the process response often reveals loop behavior that can help locate problems outside the controller. Control valve response Figure ...

“Designing Control Loops for Linear and Switching Power Supplies” is the latest book from Christophe Basso, a past contributer to Power Electronics. This book focuses on what ...

Some common examples where the control loop may not be accessible include voltage references, fixed voltage regulators and integrated audio amplifiers to name just a few.

For example, a control loop has to run in automatic control mode, be stable and responsive, and reduce process variability. Each aspect of loop performance can be expressed as a metric.

Source: Flex Power Modules Eliminating current spikes Using a loop compensation tool, one solution would be to decrease the gain until the output impedance appeared constant, or until the current ...

Closed-loop control allows single-phase ac motors to close the gap in performance and efficiency that exists between these motors and other higher-performance, higher-cost motors.
