Hi,
I'm not sure how the entire setup of the model is done, but if, for example, you want your control variable for a temparture controller to be a heating device with an SI unit of W (watt) (it could be
or something similar depending on the model setup but let's assume W here). Then K_P
should have a unit of W/K
, K_I
should have a unit of W/(K*s)
, and K_D
should have a unit of W*s/K
. When you have set up the PID Controller with consistent settings, the deduced unit for the controller appears in the Information section at the bottom of the Settings window.
Best regards,
Magnus

I'm not sure how the entire setup of the model is done, but if, for example, you want your control variable for a temparture controller to be a heating device with an SI unit of W (watt) (it could be W/m^3 or something similar depending on the model setup but let's assume W here). Then `K_P` should have a unit of `W/K`, `K_I` should have a unit of `W/(K*s)`, and `K_D` should have a unit of `W*s/K`. When you have set up the PID Controller with consistent settings, the deduced unit for the controller appears in the **Information** section at the bottom of the **Settings** window.
Best regards,
