Ziegler cone

The Ziegler cone is a concept in electrical engineering that describes a range of possible conditions for controlling a system, like an amplifier, to achieve specific behaviors. Imagine it as a "region" in a parameter space where the system remains stable and performs as desired when certain conditions—like gain and feedback—are set within this zone. This helps engineers identify safe and effective settings to avoid instability or unwanted oscillations, ensuring equipment functions reliably under various configurations.
