FLOW SYSTEM Flow Background Storage Tank Pump Flow Meter

Flow Background zInput = % motor speed zOutput = mass flow rate (lbs/min) zSSOC yOperating Range 10% - 90%

Previous Work zModeling Step Input zFOPDT Model zTransfer Function Parameters ytau=0.4secK=0.66 (lbs/min)/% yto=0.3sec where G=(Ke^(to*s))/(tau*s+1)

Previous Work zModeling Sine Input zFOPDT Model zTransfer Function Parameters ytau=0.4secK=0.7 (lbs/min)/% yto=0.3sec zBode Plots

Bode Plots zTwo Types zPhase Angle vs Frequency zAR vs Frequency

Bode Results zApparent Order is 1.8 zKcu = 2.6 (lbs/min)/% zFu = 0.8 Hz
