Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

I recently surveyed the on-site development of the control system for a large concentrated solar power station. This “first of a kind” facility offered many control challenges, such as balancing heat ...

The goal of controlling a system is to reach or retain stability. In control theory, stability is described with the Lyapunov stability criteria and mathematical models that set into relation the ...
