Re: Low Res Optical Encoders for Speed Control
We also had trouble with the 360 res quad. US Digital trying to control up to 1500 rpm with pwm. We switched to 100 res single channel, at it worked great.

Re: Low Res Optical Encoders for Speed Control
I'm not the one to go to for technical answers, but this year, we actually put our encoder on a gear reduction from the shooter so it wasn't running as fast as the shooter, and then compensated accordingly in the calculations.

Re: Low Res Optical Encoders for Speed Control
We are using a 360 count s4 encoder from US Digital, we basically use the same PID loop with feed forward that 341 does.
We were getting our shooter +- 25 rpms pretty easily. -RC Last edited by R.C. : 13-07-2012 at 02:21. |
