Hi,
I am using, cohen-coon tuning vi (Ready block in example-Autotune
PID offline), and refering the Tuning formulae as shown below for PI Controller.
Proportional value has error, where as Integral is fine.
Manual calculation for gain are as follows,
but am geting gain reading such as 0.00454352, why such kind of error?
Attached cohen-coon tuning vi for reference, how to check expression from express mode
Please suggest
Regards
