How to modelling and measure an algorithmic potentiometer in Matlab

I need to compare the output voltage of an algorithmic potentiometer with the ouput voltage of a liner potentiometer. Im having trouble finding compatible blocks in Simulink. I understand there are potentiometer blocks in the RF blockset and the regular simscape blockset but I find it troublesome to measure the outputs using the scope block. Is it possible for an example to be provided of how the simulation may be ran?

Hello Derek,

the appropriate way to model potentiometer response is using Simscape. If you are having trouble with Simscape, I would recommend starting with this free training: https://www.mathworks.com/learn/tutorials/circuit-simulation-onramp.html which has a section on op-amps. If you don't like using the scopes, I recommend using the to workspace block so you can view the data in Matlab.

Regards,

Joel
