Although some control problems can potentially be resolved through controller tuning, poor control loop performance can have several other causes requiring different solutions.

Closed-loop control troubleshooting By Jacques Smuts, PhD, PE Automation Basics Summary By Jacques Smuts, PhD, PE Every plant in the process industry most likely has several control loops that do not ...

The Control Loop Don Morgan Tuning a PID controller is pretty straightforward, once you know how to start and what steps to follow. In this series on motion control, we have already discussed ...

PID control loops are widely utilized in many aspects of everyday life and industrial automation, including gyroscopes in self-navigating cars and smartphones, flow controllers in pipes, ovens that ...

The digital twin concept is really about creating a macro control loop with many subloops covering the entire manufacturing and production operations. The digital twin uses a wide range of inputs and ...

Feedback theory It is important to know the criteria necessary for a feedback system to remain stable, therefore we need to look at feedback theory to gain some insight. Figure 1 illustrates a system ...

The non-invasive stability assessment is a method that uses an output impedance measurement to accurately determine stability without access to the control loop. The non-invasive stability assessment, ...

Driving a light-emitting diode (LED) or LED array is not without its challenges. The LEDs require a well-designed constant-current source for controlled brightness. More specifically, the output ...

Economical SOLO® Basic temperature controllers from AutomationDirect provide single loop control for heating and cooling processes using a thermocouple or RTD input signal and a relay, voltage pulse, ...

The Flexi Loop, which is part of SICK’s safety controller family, uses a single cable with an M12 plug to connect e-stops, sensors, switches, lamps, pushbuttons and interlocks. Maximum length between ...
