Ok, thanks to all for your comments. For now I'll keep the sample rate
at 1 ms and see how that behaves.If I'm not satisfied I'll remove the
jitter from the output update cycle and see if that improves anything.
Cheers,
Bas

Hello
All standard control theory books assume constant sample rates with no
jitter. This makes the maths solvable. This consistent treatment in
the books may lead to the assumption that jitter is bad. Jitter is
noise and noise is never good but is it significant? Probably not so
long as

A question for a guru who has in depth knowledge of the HAL scheduling
mechanism:
I'm developing a driver for a my servo motor controller. The interface
is via a PC parallel port. Only one RT thread is used that processes the
position feedback from the controller, and calculates the speed signa
