Packaging

No matter how well it may perform, no high-tech product will do well in the marketplace without a good user interface. Asking users of your elevator to enter enter cryptic voltages in order to get to their desired floor will not generate many satisfied customers.

When entering an established market, it is often wise to emulate the external appearance of the existing product. So the best way to package our elevator is probably to provide it with old-fashoned buttons.

Step 1:
Select a value of which you feel gives the best compromise between static and dynamic performance.

Step 2:
Load the "Elevator Control" Labview program.

Step 3:
Enter the calibration parameters you measured earlier into the appropriate fields on the panel.

Step 4:
Start the program.

Step 5:
Try selecting various floors with the buttons.

Step 6:
The Ramp control switches between setting the desired floor as an abrupt step and moving to a new desired floor in a smooth ramp. Try the controller with and without the ramp.

Question 4:
Does your elevator deliver you reliably to your selected floor? Can you quantify "reliably"?


Step 1:		Select a value of which you feel gives the best compromise between static and dynamic performance.
Step 2:		Load the "Elevator Control" Labview program.
Step 3:		Enter the calibration parameters you measured earlier into the appropriate fields on the panel.
Step 4:		Start the program.
Step 5:		Try selecting various floors with the buttons.
Step 6:		The `Ramp` control switches between setting the desired floor as an abrupt step and moving to a new desired floor in a smooth ramp. Try the controller with and without the ramp.
