Achievable position control bandwidth


#1

Hi,

What control bandwidth can be achieved with the position controller of oDrive?

I learned from a previous question that the sampling rate of the controller is 8kHz. I would assume that with that rate we can achieve about 500 Hz bandwidth in current, maybe 70-100 Hz in velocity and from there like 10-25 Hz for position.

I understand that this largely depends on the gains we select, but I would like a ball-park figure from your practical experience.

I am building a setup that would require a minimum of 15 Hz in position control bandwidth, and really need to know if it’s feasible (or at least I get close) with oDrive.

Thanks a lot!
