Assessment of the influence of the lowest mode of Vibration:

1. Make a competent iconic diagram of the sketch in figure 1. Label all elements of the diagram and indicate the elements with the correct units.

2. Simplify the iconic diagram. Give all elements labels and indicate the correct unit of each element.

3. In the model several classes can occur depending on the parameters of the system.

(a) Identify which classes can occur with this particular model.
(b) Define a set of parameters which will result in each of the given classes.
(c) What is the consequence of changing the radius of the lower wheel in the belt transmission?

4. There are 3 different ways in which we can measure the position for feed-back. Copy _figure 1 and add the three options for position measurement.

5. For each possible class found earlier, consider how the measurement operations work out and determine the transfer type that will result. Sketch the corresponding Bode plot.

6. We decide to measure the position by means of a rotary encoder on the backside of the motor, as this is easy to realize and low-cost. We could add a high-frequency roll-off filter to the control action. Are there any conditions that you want to check in this situation? Motivate your answer.
