We tackle the problem of selecting from among a large number of variables those that are “important” for an outcome. We consider situations where groups of variables are also of interest. For example, ...

This paper describes the recent efforts on developing an automotive climate control system throughout integrating an electrically-controlled variable capacity scroll compressor with a fuzzy logic ...

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 ...

March 30, 2007 Over the last century of automobile development, we have seen an enormous range of valve actuation technologies, ranging from pushrod, through single then double overhead camshafts, ...

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 ...

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 ...

Power-control modules are circuits comprising devices such as silicon-controlled rectifiers, triacs, power transistors, and power rectifier diodes. Power-control modules are circuits comprising ...

Here’s a breakdown of the various clutches and brakes used to control production speed—a crucial factor in virtually any industrial setting. Electric clutches may not be always the engineer’s first ...
