Engineering principles developed only 150 years ago were found to have evolved first in biological circuitry that controls cell growth, according to new research. In the last 150 years, engineers have ...

Joseph Juran was a pioneer in the study of quality control for industries like math and science. Learn how to apply his ...

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 ...

The internal model principle of control theory states that algorithms designed to perfectly reject input signals must contain a model of that input. Feedback control that adheres to this internal ...
