## What do you learn in Control Theory

Control Theory is all about managing dynamic systems. You'll explore mathematical models that describe how systems behave over time and learn techniques to manipulate their behavior. Key topics include feedback loops, stability analysis, PID controllers, and state-space representations. The course covers both classical and modern control methods, with applications ranging from robotics to economics.

## Is Control Theory hard?

Control Theory can be pretty challenging, not gonna lie. It combines concepts from calculus, differential equations, and linear algebra, so it's not a walk in the park. The math can get intense, and wrapping your head around abstract system models takes some effort. But once things click, it's super satisfying to see how you can predict and control complex systems.
