PID control

HI EVERYONE

Does anybody have this "characteristics of controlled system in motor speed"?

Something like the attached photo!!!!!!!!!!!!!!!!!!!!!!!

Thanks

Hello,

Does anybody have this "characteristics of controlled system in motor speed"?

 Mostly the characteristics of a controlled process is simplified or modeled by a 1st order Laplace transform that consists of a gain , one time constant and one delay time.For temperature process models, we mainly consider a 2nd order model as a good approximation.

To find a characteristic of any product that want to couple to a controller, please check the manual provided by manufacturers for valid values.If you are using more components such as VFDs, see what dynamics are added in your system.

I hope it helps,
