Re: Jaguar Speed Control Only Reaches 50% of Setpoint

It can actually execute faster than it is regulated to execute in the Jaguar.

You can't get the parameters I want like this...unless you can assure me...how many steps of integration and derivative you'll make and how long each iteration called every...apparently 1ms...takes.
It makes integration and derivative steps for as long as it's running. It does one iteration every millisecond.

The question I'm basically asking is how fast can the Jaguar actually integrate in response to a change in the input and how fast can it do the derivative. Not whether or not the code can actually do it.
I'm not grasping the distinction you seem to be making. For the purposes of the control algorithm, the code is the Jaguar.

I would like to find out or be told how to measure:
I repeats per minute and the D rate in minutes for the Jaguar PID loop.
It does one step every millisecond. Is that not sufficient information?
