CYBER-PHYSICAL SYSTEM AND METHOD FOR CONTROLLING AUTOMATIC CONTROL SYSTEM CAPABLE OF REAL-TIME AUTOMATIC RESTORATION OF PERFORMANCE AND STABILITY AGAINST MALICIOUS EXTERNAL ATTACKS AND INTERNAL SYSTEM FAILURES, AND COMPUTER PROGRAM THEREOF

摘要

Disclosed in an embodiment of the present invention is a cyber-physical system comprising an automatic control system for controlling a physical system based on a network, wherein the automatic control system includes a first control unit and a second control unit. The first control unit monitors normal operation of the automatic control system based on data processed in the automatic control system and outputs a warning signal to the second control unit when an attack is detected as a result of the monitoring. The second control unit controls the physical system, restores the second control unit based on the warning signal when the warning signal is received, and gives the first control unit the control authority of the physical system based on the warning signal.;COPYRIGHT KIPO 2019
