3. System Background

4. System Background

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

6. The SSOC

7. First Order Step Response MJB 01/25

8. First Order Transfer Function Dead Time, t0 Gain, K Time Constant,

9. Experimental Fit Results Table Experimental Fit Results tau gain dead 0-33 33-66 66-100 Question: Dr. Henry should I include uncertainty here or just let them be shown as they are in the bar graphs?

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

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

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

13. Gain Experimental vs. Model MJB 02/08

14. Dead Time Experimental vs. Model MJB 02/08

15. Time Constant Experimental vs. Model MJB 02/08

16. 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
