BE CLEAR AND SPECIFIC IN THESE POINTS.

  
a. Describe which system you are working on

--describe the "input" and "output" functions (including units) 
--describe the system's steady-state operating curve (SSOC)
--describe the system's operating range that you have chosen
--identify what you have chosen for the system's Input Baseline
and Output Baseline (include units)
--describe the system's gain (K) in the operating range (include units)
System gain (K) =
(Include units)
--describe the system's time constant (tau) in the operating range (include units)
System time constant (tau) =
(Include units)

-- describe the system's dead time (to) in the operating range (include units)
System dead time (to) =
(Include units)


Describe the system's Bode plot
  
System Order =
  
Ultimate frequency = 
(Include units)
  
(From Bode) Kcu =
(Include units)


   b. Report the amount of time you have spent on the assignment.

   c. Describe the successes & problems you've encountered 
       with the system and the concepts.
       List the ID-code for the experiments you have run. 
      (These are the titles at the top of the screen window
       of your results pages.  
       The ID-code will look like this: 012345123PM  for example.)

   d. 
--Describe the value you have chosen for your set-point and your set-point 
change (include units)

--Describe how you chose values of the integral time constant.

Identify the values of the integral time constant (tau-sub-I) 
that you use (Include units)

--Describe the data graphs you've seen 
and point out any features of the model results.


   e. Describe the results and discuss any interesting observation about the data

  f. Include your table of results in the e-mail

Table (include units)
Kc -- Tau(I) -- Decay-ratio -- Overshoot -- Offset -- Freq --  Period -- Settling Time

Tuning parameters for critical decay:
Kc =
 Tau-sub-i =
 (Include units)

Tuning parameters for quarter decay:
Kc =
 Tau-sub-i =
 (Include units)

Tuning parameters for "ultimate" conditions (Marginal stability):
Kc =
 Tau-sub-i =
 (Include units)




(Do NOT include large spreadsheet files in your e-mail.  
Copy and paste only those sections of a spreadsheet--including graphs--
that you want  to describe.)
