Application outlines
Under the circumstances of continuous output, the system whose effect ability will die down
with the change of the feedback value can do auto tune, such as temperature or pressure. It is
not suitable for flux or liquid level.
Under the condition of overshooting permission, the system will get the optimal PID
parameters from auto tuning.
Under the condition that overshoot not allowed, the PID parameters got from auto tune is up
to the target value, it means that different target value will produce different PID parameters
which are not the optimal parameters of the system and for reference only.
If the auto tune is not available, users can set the PID parameters according to practical
experience. Users need to modify the parameters when debugging. Below are some
experience values of the control system for your reference:
Temperature system: P (%) 2000 ~ 6000, I (minutes) 3 ~ 10, D (minutes) 0.5 ~ 3
Flux system: P (%) 4000 ~ 10000, I (minutes) 0.1 ~ 1
Pressure system: P (%) 3000 ~ 7000, I (minutes) 0.4 ~ 3
Liquid level system: P (%) 2000 ~ 8000, I (minute) 1 ~ 5
