1. After reading this post, we know that the so-called "position loop" of the servo is a "pseudo ring".

2. All the “closed loops” of automatic control are composed of four links: “given, feedback, comparison and adjustment”;

3, for example, the DC voltage regulation "closed loop", its regulator is "thyristor";

4. It is said that the "position loop" is a false loop because he does not have the "adjustment control link" of the motor "displacement".

5, "Position ring" is not a "closed loop" of automatic control, just a "counter" with given and feedback!
