LDRPID is the boost pid (big fucking surprise) in ME

req boost is the set point, actual boost is the process variable.

I don't understand what you are asking.

Why did you start another topic?

LDR = ladedruck regulation (boost pressure regulation).

LDRPID is... drumroll... the LDR PID.

What do you want to know?

No, it that is the I limiter to prevent integrator windup.

No. For the third time, it is the I limiter. There are still two other components, AND there is the I limiter adaptation.

Please study PIDs again.
