In Japanese
■At first
I will explain the basics of control engineering such as PID control and modern control, and the physics, mathematics, tools, etc, required for control engineering.
To briefly explain my profile, I work for an automobile-related company, where I design and develop while using control engineering.
I think that the content explained here should be understood at least when dealing with control theory and actually implementing it in things.
I would be delighted if I could contribute to the improvement of everyone's academic ability and the development of humankind.
I keep the following in mind when explaining the content.
1. Make it as simple as possible. I will explain the content accurately with less sentences.
2. I don't increase the volume of one-page articles
3. The font of the characters is not too big and there is no space between lines.(If the screen scrolls frequently, it becomes difficult to understand information)
4. I don't post image diagrams that are not directly related to the explanation of the contents.
This site is link-free. However, please note that if there is a mistake in the content, we will not be responsible for any disadvantage caused by using the information.
And I'm not good at English.
