**The portal** deals with broadly understood automatics, computer science, electronics,… The main goal is to understand the principle of “How it works”. That is why I use intuition and animation to the maximum extent. Even at the cost of simplifying the mathematics.**All courses are free.**

**First course**

**Automatics**

That is the

**flagship**of the site. The main advantage is the animations of time charts. A “static” drawing of a time chart, e.g. a

**PID temperature control**with a disturbance, is perceived differently than a waveform that develops before our eyes, I modeled each experiment with the

**SCILAB**program and then recorded it with the

**ActivePresenter**program. So the problem of knowing, installing

**SCILAB**and its operation with different settings disappears. Just press the

**video**button and watch the experiment. The note also applies to other courses. You will feel like an operator in the control room of the Refinery observing the technological process. Are you worried about the drop in distillate temperature? Fortunately, the temperature soon returned to normal. And this is simply the

**PID**controller that compensates for the temperature drop with additional heating.

I guarantee that you will know why the furnace tries to maintain the set temperature, despite the lump of ice thrown inside. Also the

**P, I, D**components of the controller will become as obvious as riding a bicycle.

By clicking the

**green**button

**“Automatics”**you will go to

**Chapter. 1 -Introduction**. All the chapters are roughly discussed here. You will see examples of animations, among others.

**Note:**

You don’t have to use

**Scilab**, a

**Matlab-like**program. For some this is an advantage, for others not necessarily. The next course is

**Scilab**. Once you know it, you can program it yourself in the so-called

**Xcos**all the experiments you learned in

**Automatics**.

There is also a version of the course with

**Scilab**->

**https://iautomatyka.pl/kurs-regulacji-pid-wstep-cz-1-34**. Unfortunately, only in Polish. There I briefly discussed the

**Scilab**. You can also download ready-made

**file.zcos**with all experiments from the Internet.

**Second course****Scilab****Vice-flagship** of the site. **Scilab** is a free program for solving various math problems. Equivalent to paid **Matlab**. Perfect for students of the universities science departments, polytechnics and even high school smart guys. Running any application, including **Scilab**, is not easy. It’s hard to describe how to enter to a specific place where you’ll be able to solve your **math problems**. For example **“How much is 2+2?”** It’s different when I use **animation**. This is also the case in other courses. If necessary, you can stop the animation or repeat it. I am an **automatics engineer**, so I devoted a lot of space to **Xcos**, which is part of **Scilab**. It is like a very shortened “**Automatics”** course. Here I analyze various **block diagrams** thanks to **Xcos**. Here, instead of tediously programming differential equations describing a given **Automatic Control System**, you simply draw a block diagram. Then you press the **“Start”** button and enjoy the viewed time course.

Four on Series and Fourier Transforms**–** **Complex Numbers** as something needed for **Fourier Series and Transforms**.**– Fourier Series Classic**As the name suggests.

**– Rotating Fourier Series**

That is

**Fourier Series**in a different way. You throw a periodic function

**f(t)**into a centrifuge. And what comes out of it at the appropriate velocities

**1ω0…, nω0**? Consecutive harmonics of course!… This approach is more intuitive than

**Fourier Series Classic.**

**– Fourier Transform**

Most authors start with this. It does not say what the

**Fourier Transform**is, but how it is calculated. It’s as if someone defined a

**hammer**as a product that needs to be made in a certain way. And it should be. A

**hammer**is a tool for driving nails, and the

**Fourier Transform**is a method for the

**distribution of harmonics**in the

**f(t)**signal.

I’m thinking about the

**Laplace Transform**. All in all, it would be a nice whole.

**– How does CRC work?**

When the

**2**networked computers conclude that the information received is not the same as the information sent, they repeat the transmission. That’s how the network works. Okay, but how do they know there’s been an error?

*****One king send another king a very important letter that decided about war or peace. How can they be sure that the bribed messenger hasn’t changed a few but very important passages in the letter?

* Of course, I am not thinking about the trivial case when the receiver sees only bushes. But, for example, when one dot is missing or changed to another character from 100 uploaded pages.

**– Cyclic Buffer**

A computer that wants to send a larger number of bytes first puts them into some area of memory. This relatively small memory can be, among others,

**Cyclic Buffer**.
