Lab 6 Overview

For the lab, we used a fader motor, as it is the component that we will be using to haptically simulate the strings of our virtual guitar. Given that we had not previously performed a system identification for this fader motor, we cannot provide a comparison with the experimental frequency response plot.

Though we cannot provide a direct comparison, we can make judgments based on our observation of the motor behavior and compare our experimental plot with those. For example, as is apparent by the fact that a sound comes from the motor when we run it, there is metal on metal contact, which leads to a great deal of friction in the system. Because of this friction, system identification should return an overdamped system. Overdamping was definitely the case for the lab.

For future purposes, we plan to perform a system identification by loading a variety of masses on the fader motor so that, in the long run, we can better understand the system instead of just making judgments and best achieve the behaviors we want for our virtual guitar.
