Reveal the motion servo

2018-05-14 00:00:19

Motion servo system, belongs to the category of automatic control, but simple to understand. Simply put, the output can follow the input with a certain degree of accuracy and change the system called servo system, also known as servo system.

Tools/Materials
1

A certain cultural foundation

2

A certain ability to understand

Methods/Steps
1

The composition of servo system: 1. Controller 2. Power drive device 3. Feedback device 4. Actuator (mostly electric, etc.)

2

The function of the controller is to compare, judge, and command. Kind of like a command post, comparing feedback with requests. Determine whether you need more or fewer commands. Finally give the command. Adjust the control amount.

3

The power drive device, in fact, is to convert the command signal into the execution signal, generally amplified. Power amplifier, play the audio signal out loud.

4

The feedback device, as mentioned earlier, the servo system can follow a certain precision, and without feedback, the precision of the execution cannot be known, and it cannot be adjusted. Let a person 100 meters, without feedback, there is no way to know how much he actually ran.

5

The actuator is the executing part of the system, which can be a motor, or a heater, and so on. The actuator corresponds to the output. The actual function of the system is the executive mechanism.
