Power plants–especially coal-fired boilers–pose a set of process control problems unparalleled in other industries. Rapid load ramps, continuous unit demand changes, variable fuel quality and process ...

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but experience ...

Steve Sandler explains what every engineer should know about ‘non-invasive’ stability assessments. The non-invasive stability assessment is a method that uses an output impedance measurement to ...

How to read Bode plots to assess dynamic control behavior of a power-supply design. Observing Bode plots from an example voltage regulator to observe control-loop speed and stability. This article ...

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 ...

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 ...

Honeywell Industry Solutions announced recently that it has analyzed performance data from more than 100,000 control loops at 350 manufacturing facilities since the introduction of its Loop Scout ...

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 ...

The course is focused on current-mode control techniques, which are very frequently applied in practical realizations of switched-mode. Upon completion of the course, you will be able to understand, ...

Loop analysis of analog and mixed-signal discontinuous systems, such as PLLs, delta-sigma converters, switched-capacitor filters, PWM amplifiers, and switch-mode power supplies, presents a unique ...
