This application note describes a closed loop, computer- controlled, variable attenuator for the control of output power from a tunable laser. It is based on the combination of a 1/2 wave-plate and a ...

The low-voltage variable speed drive (VSD) allows variable control instead of fixed-speed operation. These days, VSDs can ...

An electronically controlled CVT that is used as a transmission on off-roading buggies that offers experience in testing, programming, and electrical work. A CVT is a type of transmission that ...

Part one of this three-part series examines the rational for using control technology to reduce process variability ...

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 ...

In science, a variable is something that can be changed, measured or controlled in an experiment. Scientists look at variables to understand how they affect things. A variable is any one of the things ...

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 ...
