Abstract :
ACONDITIONALLY STABLE SYSTEM is a feedback device which is stable for the designed operating conditions but which becomes unstable if the over-all gain is reduced. When a servomechanism is designed for optimum performance, the final system is frequently found to be conditionally stable. The behavior of this class of systems is reliable, provided that operation is confined to the linear regime throughout.
