How to be confused as fuck in four minutes!

[chevon1920]

Well that took more than 4 minutes, but I do definitely understand it much better. THANKS SO MUCH!!!!!

Would have been better if somebody have spoken simultaneously with the video!.. a short and a good watch indeed.

[ElrondtheSchlong]

very good!

Basics adjustments that need to be made in order to get the same result after a derivative is thrown into play. In order to get the same result before the derivative. I can dig it, good video, but we need some music man!! LOL

@amrosik Your explanation really helps! Thx a lot :D But can you also try to explain what does the I - component does using that analogy of the car? Thanks again!

Excelent Video!!!

Thank you for the great explanation. Really helpful. :)

Great summary of all the important things!

@joeballardjrband ... approaches the line. then the error decreases, thereby the dx/dt is negative, and in sum P+D is smaller than P alone(because D is negative). and if this new output is fewer, then the driver will steer fewer, and as a result the car will swing over fewer.

now clear?

[amrosik]

@joeballardjrband ok, then consider the folliwing: look at the picture at 2:19....

this is the case were you only response over linear correction. a practical example: a driver wants to follow a straight line on the floor... everytime he approaches the line, he still has momentum. this momentum causes the car to swing over the line.

now, what does a D-component do? the D-component involves the information about the momentum of the car. how does that D-komponent act?imagine the car approaches...
