Stability margins

Stability margins are measures used to determine how much a system, like a machine or control process, can handle before becoming unstable or oscillating wildly. They indicate how close the system is to losing control. For example, in electrical power systems, a stability margin shows how much additional load or disturbance can be added before the system becomes unstable. Higher margins mean the system can better tolerate changes, ensuring safe and reliable operation. Essentially, stability margins provide a safety buffer, helping engineers predict and prevent potential failures.
