Design PID Controller

Control System for Sensitive Teeth

  • Design PID Controller for toothbrush
  • Controller will optimize based on user’s (child’s) teeth sensitivity

Harsha Alva I am little confused, then what is the purpose of PID Controller. There should be an actuator for whom PID is to be designed, isn’t it? . otherwise simple get data from sensors send to phone for processing. Please clarify me a bit.

You guys are on the right track. It’s hard for me to perfectly manage this, so I will say, do your best and submit a final design in what ever format you’d like either directly here or via google drive.

It is excellent to diagram and determine all the components needed. But all I am looking for is transfer function, block diagram, parts used, etc. We are not going all into designing this for real. Is that clear now? I am trying my best to simplify this so it is a fair task.

I don’t think a PID is required for this project. It’s as good as an open loop controller. The user can decide to put the brush away in spite of the warnings from the app.

the pressure will be applied by a dc motor i think as we can see the 3d model submitted for this brush. am i right Ethan Schur? And please also let me know who we will know the sensitivity of child’s teeth in order to use it as feedback for PID?

A lot of great points. I can’t get into this detail at this point in time but I still want to complete this challenge.

Let’s say:

We are just looking for block diagram. For 2 axes of sensitivity.

Assume there is a pressure sensor.

Users hand will be actuator however assume that mechanism to be a visual process that the child sees when he is brushing too hard. You can just assume certain values. I am looking for just a block diagram.
