Outline System Background –Description, SSOC, Step Response FOPDT Modeling Experimental vs. Model Results Conclusions

System Background

Steady State Region Steady State Input M(s) Output C(s)

The SSOC

First Order Step Response MJB 01/25

First Order Transfer Function Gain, K Dead Time, t 0 Time Constant,

Experimental Fit Results Table Experimental Fit Results taugaindead Question: Dr. Henry should I include uncertainty here or just let them be shown as they are in the bar graphs?

FOPDT Model Equation Will include the Model parameters for this graph similar to table in previous slide

Input Model Output: Purple Curve Experiment Output: Red Curve Step Up 33% to 66% Input FOPDT Model MJB 02/04 Will Probably OMIT this slide and use the next one

FOPDT Model Model and Experimental Input Overlap Model and Experimental Output Overlap Step Down 66% to 33% Input MJB 02/04

Gain Experimental vs. Model MJB 02/08

Dead Time Experimental vs. Model MJB 02/08

Time Constant Experimental vs. Model MJB 02/08

Conclusions Linear SSOC – Slope represents Gain Reliable Operating Range (0-100) % Small Uncertainties FOPDT Parameters: Model vs. Experimental Similar Similar Uncertainty, relatively small Model shows FOPDT parameter are constant
