Also known as feedback loop, feedback process
概念
Feedback is when the results or outputs of a process loop back around to influence that same process as inputs. It matters because these loops can either stabilize a system (like a thermostat maintaining temperature) or cause it to spiral out of control, making feedback a fundamental mechanism that shapes how systems behave.

回饋（英語：feedback）又称回馈、回授，是控制論的基本概念，指將系统的輸出返回到輸入端并以某种方式改變輸入，它们之間存在因果關係的回路，進而影響系统功能的过程。 在這種情况下，我們可以說系统“回饋到它自身”。在討論回饋系统時，因果關係的概念應當特别仔细對待： “對於回饋系统，很難作出簡單的推理歸因，因爲當系统A反馈到系统B，系统B又反馈到系统A，形成了循環。這使得基于因果關係的分析特别困難，需要將系统作爲一個整體來看待。” 反馈可分为负反馈和正回饋。前者使输出發揮与输入相反的作用，使系统输出与系统目标的误差减少，系统趋于稳定；后者使输出發揮与输入相似的作用，使系统偏差不断增加，使系统振荡，可以放大控制作用。对负反馈的研究是控制论的核心问题。
