Hello all,
I have set up a PID loop which works fine except it is a bit slow during the startup.
I wish that it would reach near the setpoint faster. What should I look into?
The PID controls the flow of a pump. I am happy after the startup, it is only the startup I want to improve.
It takes about 15sec to stabilize.
I noticed that if I make P larger and I smaller, then I get a faster response and big overshoot followed by a big undershoot. If I remove D then I get a huge oscillation until it stabilizes.
P=0.004
I=3.2
D=0.935
