System Feedback
A mechanism where a system's output affects its input, creating self-regulating or self-amplifying cycles that control growth, stability, and behavior.
System Feedback
System feedback represents the cyclical process where a system's outputs loop back to influence its inputs, creating dynamic patterns of regulation and change. This fundamental mechanism underlies everything from biological homeostasis to modern control systems.
Core Principles
Types of Feedback
-
Negative Feedback
- Reduces deviation from equilibrium
- Creates system stability
- Examples: Homeostasis, Thermostat Systems
-
Positive Feedback
- Amplifies changes
- Can lead to Exponential Growth
- Examples: Population Growth, Chain Reactions
