Relation between open loop and unity feedback close loop response

Click For Summary

Discussion Overview

The discussion revolves around the relationship between open loop and closed loop responses in control systems, specifically focusing on unity feedback systems. Participants seek to understand how these two types of responses relate to each other in terms of system behavior.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant asks for assistance in matching the open loop response to the closed loop unity feedback system.
  • Another participant questions whether a specific line in the response graphs is meant to be straight, implying a potential misunderstanding or need for clarification.
  • It is suggested that if the open loop gain is sufficiently high, the closed loop response with unity feedback could approximate Vout = Vin.
  • A participant provides a link to external notes, indicating that further reading may clarify the relationship between open loop and closed loop responses.

Areas of Agreement / Disagreement

There is no clear consensus among participants, as questions and suggestions indicate uncertainty and differing interpretations of the responses.

Contextual Notes

Participants have not provided specific definitions or assumptions regarding the terms used, which may affect the clarity of the discussion. The mathematical steps involved in relating the two responses remain unresolved.

hi!
can someone please help me with this problem...i have to match the open loop respone to the close loop unity feedback system of a control system.

what is the relation between the two?


thanx in advance

these are the two response..
can some one please help now...

than in advance

Is line "A" or "B" meant to be straight?

If the open loop gain is high enough the cloosed loop response with unity feed back is Vout = Vin.
