Multiple PID - federicocilla71@gmail.com - 16.01.2017
Goodmorning everyone.
I have a problem I can not make more PID function simultaneously.
Can someone help me. Thank you
RE: Multiple PID - admin - 16.01.2017
Like this:
Code:
if not p1 then
p1 = PID:init({
current = '1/1/1',
setpoint = '1/1/2',
output = '1/1/3'
})
p2 = PID:init({
current = '2/1/1',
setpoint = '2/1/2',
output = '2/1/3'
})
end
p1:run()
p2:run()RE: Multiple PID - Erwin van der Zwart - 16.01.2017

good morning, thanks for the kind risposta.ma I can not upload the files you sent me. Can you help me.

Hi,
The files are not export/import format but manualy created.
Just open them with a text editor (notepad++ or wordpad or something) and create a user lib called 'pid' and a resident script and past the content manualy to them.

thank you so much
RE: Multiple PID - federicocilla71@gmail.com - 17.01.2017
still one last question. To slow down a bit the speed of PID how they work the following values? :
kp = grp.getvalue ('3/3/105'),
ki = grp.getvalue ('3/3/106'),
kd = grp.getvalue ('3/3/107'),
Thanks again for your valuable contribution.

Hi,
This is project / system configuration related, i would start with 0.3 for all and from there fine tune between 0 to 1 if you need to reduce overshoot or need more agresive loops.
