1. Green Team Dustin Fraley DeAndre Strong Stephanie Wilson September 14, 2005 UTC ENGR 329 Speed System

2. Presentation will include… Background on the speed system Theory of experimental analysis Steady-state and step tests Results of tests Conclusions on the usefulness of our findings

3. Background: what is the speed system?

4. In other words… SRC 1 ST 1 Motor / Generator SCZ 1

5. Theory

8. Results Cont. Steady-state Function C = 17.28 m – 9.66 Input Range 20% - 90%

9. Time Response of the System

10. Using the Fit 2 Method

19. Conclusions The SSOC accurately predicts the output of the motor (input 20%-90%) Tau, K, and t 0 are approximately the same for input upsteps and downsteps.
