The Flow Lab.......
• The apparatus......
• The control system......
• The SSOC......
• FOPDT model vs. Flow System........
==============================================================
System input:
% Of motor speed from computer. (%)
System Output:
Water flow reading from flow meter.(lbm/min)
Operating Range:
Due to dependence of pressure for the solenoid valve to work properly, our focus will be above 50% motor speed up to 90% motor speed.

Why is this important?
Most controller-tuning formulas are
based on this model.
The Results:
( +.01 unless noted )

Final Results:
Fathom Group
FOPDT step response results
Gain 0.33 + 0.01
Dead Time 0.32 + 0.14
Time Constant 0.58 + 0.25
