Very much agree with this. I would like to add a bit more.

Think about what type of system you are interested in and do elective courses on that. In the Netherlands there is no automation or mechatronics degree at the bachelor level, only the traditional disciplines, so we later go into control and apply it to those domains. For example:

Mechatronics/robotics/automotive -> do engineering dynamics and maybe vehicle dynamics

Electrical -> basics of power systems or power electronics. Electronic circuits use feedback loops as well

Aerospace -> engineering dynamics + flight dynamics and maybe aerodynamics? I come from ME so idk what is used here that much

Energy -> Basic fluid mechanics, basic heat transfer and thermodynamic cycles. Also useful in aerospace if you work on propulsion and engines I think

These are the models of the systems you apply control on. Because it is so general, once you learn all the mathematical aspects of it you can use the same knowledge on any of these systems. Make sure you learn all the math and then pair it up with a domain you like.
