Feedforward component in PID tuning (DBW)
Posted: Tue Feb 04, 2020 7:58 pm
Hi all. While I was tuning a pid (drive-by-wire) on my m800 I noticed the section "feedforward". I know that feedforward consists of sending a percentage of the input directly to the output with no control action.
How does this affect the behaviour of the system? How can I choose the correct value while tuning the PID without damaging the ETB? Using the feedforward component could reduce the lag between TPD and TPS?
Thank you for your support.
