1.2 Optimizing P gain
While optimizing P gain, the gas flow determined above has to be constant all the time.
Start optimization with P gain set to 1.0 and I gain set to 0.0.
Set chamber pressure to SP2, wait until the pressure is stable. Set pressure to SP1. If the transition from
SP2 to SP1 results in a significant pressure over shoot or even does not stabilize at all, the P gain is too
high. If there is no over shoot and the pressure reaches SP1 asymptotically and very slow, P gain is too
low.
The optimal P gain value is found if the transition from SP2 to SP1 results in a slight pressure over shoot.
It does not matter if there is still a deviation between SP1 and actual pressure.
