Hi All,
I am attending an Electronic Engineering course and I bumped into a though topic: control system.
Could any of you kindly explain me what it is about?

Control theory is a large area in mathematics that is also used extensively in engineering and some other fields.
You need to be a lot more specific about what your issue is.

So control systems is the art of analysing, modelling, and controlling systems. What this means in practical terms is that when you switch something on, it doesn't immediately switch on i.e. 0 becomes 1, there's a few steps inbetween which complicate the process, for example it may take 1 second for the value to go from 0 to not 0, and before you get a steady value of 1 it might overshoot to 1.5 and you might get oscillations. Control systems is designing a controller to get that value to 1 in an acceptable way given your system and the performance requirements, e.g. your system overshooting to 1.5 might mean it takes lower to settle down to 1 compared to if you only overshot to 1.2, but equally you may get close to 1 slower and you may value a quicker response over a response which doesn't overshoot. A classic example of this is cruise control, if your car goes 1.5x the speed limit, that's a problem. Or your car might not be able to do 1.5x the speed limit, so you have system constraints, which is another problem.
There is also the modelling aspect, where you take some data and use system identification techniques to determine relationships within that data, essentially mathematical models which say, e.g. if I put this much power into a motor, how fast is it going to spin at time t?
You will also find robotics comes under control systems.
