Control Theory is one of the specializations in Electric Engineering after 1945.
Electric Engineering used to be founded (as a study) during the 1880ties.
Precisly after the whole fundament of Michael Faraday ("Turning Magnetism into Electricity"/1821).
The other specialization was Information Theory after Claude Shannon (1944, earlyer before release) , which paved the way towards "Telecommunication or IT".
So whenever people might refer towards Electric Engineering with the connotation, that describes it to be hard, then it is solely because every inventor of our modern textbooks from Physics with Schrödingers Equation in the 1940ties) until Computer Science (who held as their previous title "Electric Engineers" (until the 80ties) originated by the concepts of Control Theory.
Control Theory doesn't only originates before the Roman empire, but it also is the study to regulate and control (translated combined in to either "regulating" or "steering") any physical system. Either our own breath, our time or our own machines.
These Feedback Loops paved the way for "Artificial Intelligence" to unterstand, what is "control" ?

Control Theory requires starting from the constant flow and precision to hold the signal at any cost stable.
Many Engineering Graveyards are founded, whenever the system became too "unstable" in the imaginary belief.
From the big Takoma Bridge to the first bigger ships, until trains with exploding temperature glas scales, there was the need for better sensitivity in the sensor and robust actuators.
"Optimization", "Prediction" or "Nonlinearity" was key for better and safer tools.
(Luenberger Modell, Kalman Filter, Vortexes etc.)
Nowadays Swarm Control, Multiple Sensors, and higher Degree of Nonlinear Equations are heavily applied on small form factors. (also bio-medical application) High-temperature or fine-scaled actuators & sensors are relevant (coatings).
Regarding more intro to Control Theory, Check out: Brian Douglas's Video.
Via Rapid Prototyping (Matlab, orig. Fortran) are control systems faster simulated & designed for the use-case.
> Bodeplots and co. will be listed.
Remember, that a PID Regulator can be created by an Op-Amp Circuit (P, Integrator, Differential) or even via a digital PID.)
In the literature they would call it in the context of Control Theory as a regulator, while in the broader signal processing context, it is a filter/kernel. Very important. They are the same.

"A large section of the report was devoted to the delay line, a cheap high-capacity electronic memory that Eckert had invented early in 1944. Before meeting Mauchly, he had applied his electrical engineering wizardry to the wartime development of radar systems. One goal of that work had been to find reliable methods of distinguishing between signals from stationary and moving objects. Eckert’s ingenious solution was to turn the incoming electrical radar signal into sound waves and pass them through a tube filled with mercury. The signal could be recovered at the other end of the tube by converting the sound waves back into electrical impulses. The length of the tube was chosen so that the signal was delayed long enough for the radar dish to turn through one complete revolution. The delayed signal could then be subtracted from the new signal to leave only blips from objects in motion. While working on the ENIAC, Eckert realized these ‘mercury delay-lines’ could be used to store and retrieve data. Data could be stored more or less indefinitely in the tubes by feeding exiting signals back into the device and could be overwritten by ‘catching’ the relevant set of pulses as they emerge from the tube and replacing them with the new data. Depending on its length, a delay line could store hundreds of digits."

Note:
It isn't just machinery and motion.
Control Theory is a mathematical construct, that can be applied universally in all sorts of areas.
Every stable system has component with time delay, sensory feedback (or thought forecasts) and a reponse.
Being to fast, isn't the most of the times stable.
