I and P Term Balance | Oscillations & Wobbles

[@adilsongoliveira]

When I was 14, I started an apprenticeship school for industrial measurement and control (yes, we used to start young here) and there I learned about PID. As I never progressed in this career (I went to electronics and IT after that, today I'm a technical account manager at google) is interesting how it came back to haunt me in my hobby 😁

[@someonespotatohmm9513]

The way I prefer to think of the I term is as an offset compensation. Because a feedback controller needs an error to produce a control signal, it will never reach a setpoint requiring control effort, the integral term is an attempt to learn the control effort required to reach a setpoint.

Thank you for another great “layman” explanation of the PIDs. Best wishes in 2024!

[@novisfpv]

wow. .. this is great. am now getting a grip of what PID means

[@arminsky575]

💯 quality content , graphs-animation makes it really easy to understand , well done . THX a lot 👍

[@cedric4893]

Very interesting and this makes lot of sense! Still learning everyday 👍 Thanks for your great video, really helpful 🙏

[@lalbabugupta8380]

Quality content. As always thanks sir

Great way to break down and communicate how I term works. I really needed this! In betaflight I term relax doesn’t run during fast throttle inputs right? Seems like some I term windup happens here too but maybe I term can’t be clamped due to throbbles 🤔

[@uavtech]

no it does not. for fast throttle moves, Anti-Gravity boosts P and I-Gains. If you have any wobble, you may need to increase the P ratio for that in the CLI. It boosting both is correct, but it may require more P in the P / I balance.

[@chrisburke63]

@@uavtechthanks! I’ll give that a try

[@jorgeromero4680]

excellent

[@Simofly]

How is the difference from external factors ( wind or any non set point input ) , between I and D ? Are they completely uncorrelated in this case too ? ( for a quadcopter )

[@uavtech]

it works the same either way between I, P and D (external change or Setpoint change).

[@theaman4005]

Nice video 👍🏻. I (excuse the pun) imagine the d term is not having much of an effect on the I term - because the oscillations are slow. D term responds to rate of change, not the quantity of change. Interesting enough, as the d term was increased - the oscillation became even slower, which would cause the d term to shrink. Is this the opposite to d term oscillation? 😂

[@uavtech]

basically, right. :-)
