The compensation of any process deviation that could lead the system to an instability threshold.
The control of errors by feedbacks was at the origin of cybernetics. It aims at dynamic stability in processes and systems by maintaining their fluctuations within predefined limits. It was discovered and practised empirically various centuries before the theoretical work of N. WIENER.
Error control is obtained through the iterative measurement of errors, used by the control device as data to determine by comparison with the established stabilization standard the needed counteractive action. See: “control by error”.
