I do not use integration, because winds up and does not center well, just flux=V-(i*r) *(1/freq)-L(i-i_prev), then LPF as an pseudo...

I found this document https://s3.amazonaws.com/scolton-www/motordrive/sensorless_gen1_Rev1.pdf that discuses FOC but the interest is the...

@mxlemming , i have a question regarding SI units for the inputs of the flux observer, "flux_a = flux_a + (Vab.a - m.R * Iab.a)*...

O yes, that is crap for switching, this setup is just some beefy parts that i had around and would be strong enough to drive my ass...

well some of my hall noise was caused by slow FETs (IRFP4468 with added 33nF on gates. This is test setup) and not enough dead time...

hy, thanks for your input, i have looked on it, will think about it and learn. In the mean time, i figured out some things, first is...

I have made the hall implementation, without interpolation works great, good torque all that. I have also made hall sensor...

Well a comparison could be in car drifting, FWD car you have to have a good and use the handbrake, a RWD car you need to have some HP in...

i did manage to tune the PID a bit more, i did have the issue of not using S.I. units for the values of all the parameters, voltage...

that may be... well this FOC stuff has a lot of parameters, many of them need a good explanation of what do they do, so far i'm...

it has front brakes, they do work very well isn't super heavy, it weights about 35kg without battery, it has to be strong i'm quite big...

well, the main reason for no foot rests on the frame is that i do not like how it looks, second, it ads weight and size to the frame...

After i replaced the dead cells from battery, i charged it up, it took 45Ah, but wasn't completely drained down. Sunday went flying, did...

The main usage of these FOC is for terrestrial use, this is my test platform project Electric Drift Trike Build Did you had problem...

i'm back with updates, had to change the rear tires , they ware to large and did not fit the 250mm OD plastic pipe, i painted the frame...
