PID control output

Hello,

Greetings. I have applied the PID control method in my experiments (code attached). The goal of my experiment is to maintain a target fertilizer/nutrient level of a hydroponic cultivation system. We know, PID output is the sum of Kp, Ki, and Kd. I have to show the individual coefficients output in my paper during the PID application. I opened the PID VI (picture attached), but can't find out the specific output point of those coefficients. Any kind of help will be appreciable.

Hi milon,

 

do you see those "derivative action" and "integral error" comments on the right?

The proportional error is calculated by multiplying kp with error: just look out for that multiply function...

Best regards,
