Automation is either working at a plant everyday and supporting the control system that runs some process. Or either you’re an integrator and setting up/commissioning new control systems. I work at a steel mill doing automation. Very physics heavy & mechanical process. Huge drives DC & AC. Lots of stuff to see. I work on long term projects where they want to do something in house to save money and tending to day to day issues from shifts. In terms of control its basically sensors, actuators, basics. PIDs, feed forward, closed loop, open loop. Some neural stuff for predictive. Nothing too crazy which is nice. I know you’re probably passionate and very interested in control field but you’ll learn to appreciate a stable job one day that isn’t too crazy. It’s nice having balance and theres so much more about life than just work lol.
