set "PID parameters" for power serie of y = 3E-40*x^18.94
set "PID parameters" for power serie of y = 3E-40*x^18.94
(OP)
Hi,
How can I set "PID parameters" for the control of the system with the following "power serie" ?
y = 3E-40*x^18.94
X min = 30
X max = 90
PID parameters:
iMax,iMin,
pState,istate,dState,
pGain,iGain,dGain,
MAX,MIN
regards

What plant has such an extreme y=f(x)?
Going from x=30 to x=90 means zillions of orders of magnitude change in y. Are you sure you got that relation between x and y?

68.8 1.00E-05
73.7 8.90E-05
78.6 2.00E-04
83.5 6.40E-04
are some of points.
at main working area X is between 60 and 80

PH?
This a chemical reaction?

You can often map the valve if things permit then run via a table that takes into account the actual flows that 'will' occur.
Or model the valve and run with the model in the 'plant'.

but it will not work with LOOK-UP TABLE
- input is voltage for gas paffing valve control
- turbo vaccum pump run continuously
- output is vaccum
