Proportional Gain and Proportional Band (ENG.)
Source: > Engineering Technology Simulation Learing Videos
In a closed loop system, a controller is used to amplify the amount of output change in proportion to the change that occurs at the input. Controllers provide amplification using one of two modes of proportional functions; Proportional Gain and Proportional Band. Watch this video to learn more.
What PIDs do and how they do it (ENG.)
Source: > RCModelsReviews
In this video I try to explain in simple terms, the black magic and voodoo that happens in a PID system, such as the ones used in our multirotor flight controllers like the Naze32 and CC3D. As usual, I've take a few liberties to make it easier to understand what can otherwise be a very complicated subject.
