?? The feedback principle is described as follows:
1) introduce feedback:
2) If there is feedback, change it.
This principle tells us that we should collect as much feedback information as possible from the system and use this information to correct the role of the system. It is easy to see that feedback is introduced
Is the prerequisite for automatic system control. The information generated by any changes in the system can be considered as the feedback information source. Of course, the specific collection needs to be determined based on actual needs.
Through the feedback of system operation, we can understand the running status of the system.
Such feedback includes not only system feedback, but also environment feedback during system operation. If necessary, it also needs to be collected because the system must exist in the environment.
Feedback principles are widely used:
A) Automatic Navigation and automatic process control:
B) Sound Control lights and automatic door prevention:
C) Customer Satisfaction Survey and product market share survey;
......
Self-control, self-service, and self-maintenance in the ideal system all need to introduce feedback mechanisms in the system. Therefore, the system should take the feedback mechanism as an important part during the design;
In software systems, such feedback mechanisms are also ubiquitous, such as heartbeat mechanisms, user feedback, and user habits.
