how Large my PID Coefficients can be ?

Hi

im designing a pid controller for a suspention system and im tuning the PID with swarm algorithms !

when i define a larger Coefficients i get such a better answers (like when i set to 100000000).

but is there any problem with that?

is that a limitation?

should i choose a lower band for my Coefficients ?

thank you so much for helping me .

hello

IMHO, first thing to do is to have a valid model of the transfer function of your suspension system

then define what the controller requirements are, what is the role of the P, I, D term

there is maybe a simpler first approach to PID tuning vs jumping in first place into heuristic methods

thank you for your suggestion

i have tuned the controller with different methods and im just compairing them

thats why i have done this with heuristic method

[Mathieu NOE]

have you tried this one ? (from fex)

[ahmad ahmadi]

thank you for sharing this code

hopefully i dont have problem with compairing or running the codes.

i just wonder how large can i set my Coefficients for tuning the PID since in my case ' Larger ones cause much better performance '

hello

so how does the model of your system looks like ?

have a code to share ?

all the best
