Was going to suggest Kalman but then i saw it at the bottom of the ocean. I think Filters that are easy to implement are the best in most scenarios
@gergelybencsik8626
@gergelybencsik8626 Месяц назад
Indeed, and I find the 1st order lowpass to be the simplest, and it gets the most use. Kalman Filter is powerful, but overrated. I'd love to get there eventually, but sadly I don't have time for videos these days

Brilliant. New subscriber question: What's the average percentage difference in slip-free rotations vs. real-life rotations with slip for an average situation, say Honda accord driven gently vs spiritedly (lots of acceleration) at something like 120 km/h on average? Is it "a couple percent" or more like 0.1 or less%
@gergelybencsik8626
@gergelybencsik8626 Месяц назад
Sorry, I don't have experience with the numbers in this field. I looked into the theory of it but I haven't worked on anything like that you need.
@PeterBaumgart1a
@PeterBaumgart1a Месяц назад
@@gergelybencsik8626 Understood, not asking for an exact answer, just an estimate or educated guess. The amount should break down into actual wear-inducing slip (wrt to the asphalt) and just "flex" in the side wall and tread, agree?
@gergelybencsik8626
@gergelybencsik8626 Месяц назад
@@PeterBaumgart1a Weelll, really uneducated guess is about 5% slip before it's sliding. However, keep in mind it's never a contact point, but a contact patch, and there's partial sliding in some percentage of the patch. So you'll get some wear even if you drive in a way that it never really slides.
@PeterBaumgart1a
@PeterBaumgart1a Месяц назад
Nice! Regarding your last argument: It can be shown mathematically that there has to be sliding, or rotation will not be smooth.

@gergelybencsik8626
@gergelybencsik8626 3 месяца назад
Sorry I haven't looked into that one. The line of action is a bit more mind boggling for inner gear but a very similar derivation should be possible for it.

@gergelybencsik8626 3 месяца назад
Thanks :) The truth is, I'm more of a software and control guy. The video idea about gears kind of came to me randomly, and I think I did the best I could, but from this point onwards, I really lack experience. I'm thinking of building something as one of the next projects and I might use 3D printed gears for that, but there's really not much more I can say about the science and engineering of gears.

*Abstract:* The video provides a comprehensive overview of the Exponential Moving Average (EMA) filter, a fundamental tool in signal processing. The presentation covers the filter's basic properties, implementation, and applications. *Key Points:* * *Definition and History:* The EMA filter is a first-order, low-pass filter with origins in 19th-century mathematics. It calculates the output (y) by recursively combining the current input (u) and previous output (y) with complementary coefficients (alpha and 1-alpha). * *Tuning:* The time constant (tau), which is the inverse of alpha, is a more intuitive parameter for tuning the filter's behavior. * *Implementation:* The EMA filter can be easily implemented in code due to its recursive nature. * *Properties:* * *Delay:* Causes a delay between 1 and 3 time constants. * *Cutoff Frequency:* The cutoff frequency is the inverse of the time constant (tau). * *Noise Reduction:* Reduces white noise with a factor related to the time constant. * *Comparison to Simple Moving Average (SMA):* While both filters offer similar noise reduction and delay properties, the EMA has advantages in memory usage, ease of implementation, and adaptability. i used gemini

I give up, how can this be a dc motor if it is powered by 3-phase ac?
@gergelybencsik8626
@gergelybencsik8626 4 месяца назад
You're right, it's technically AC. The term 'Brushless DC' is actually more like a marketing term. These 3-phase permanent magnet motors, together with their motor driver circuits (ESCs) were first marketed and popularized in the industry as a replacement for DC motors. The motors that inspired this whole video, the ones I'm specifically talking about here are 'Brushless Outrunners'. They're used in drones and RC planes everywhere, and use the 12s/14p config all the time.

I like the explanation, but the background noise makes it very hard to follow your description. It would be much better without the sound effects running. I know that is supposed to be artistic, but for a lecture it is pure distraction.

@gergelybencsik8626
@gergelybencsik8626 5 месяцев назад
I moved on to different topics with newer videos, may return to something like this in the future, maybe not. This is actually a Roots-blower, a kind of compressor. But the design principle is cycloid gearing, which is different to involute gears, you can look into them if you're interested.
