The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

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 ...

Just over a decade ago, an article titled, "Advanced Control Strategies Move into the Field" (Control, October 2008), highlighted three evolving trends in the process control world that would "make ...

Soft starters and VFDs both effectively control motors and are efficient users of energy. Determining which technology to use depends on understanding the performance needs of the application. A ...

In his new book, AI expert Hatim Rahman argues that algorithms have created a new labor market paradigm for workers. The rise of high-speed internet in the early 2000s transformed the global labor ...

Highway speed control is a difficult task for municipalities. They erect signs to notify drivers of the local speed limit, but that is not always effective. The town of Woodstock, however, has ...
