Hello Mark,
Thanks very much for the reply on the PID record. I checked the
PID code and found that what you say is true. The code for the
i term is:
i = kp*e*dt*ki;
so you are correct and this is why when the KP term is zero the
PID filter does not work.
As for your EPID record I would be interested in giving it a try.
Do you have a URL where I can get it. Does it have documentation?
Do you have a Capfast symbol for it or do I have to creat one myself.
Thanks you very very much for the reply and look forward to
evaluating your EPID record.
