Abstract

This paper presents a new data-driven fault identification and controller\nreconfiguration algorithm. The presented algorithm relies only on the system's\ninput and output data, and it does not require a detailed system description.\nThe proposed algorithm detects changes in the input-output behavior of the\nsystem, whether due to faults or malicious attacks and then reacts by\nreconfiguring the existing controller. This method does not identify the\ninternal structure of the system nor the extent and nature of the attack; hence\nit can quickly react to faults and attacks. The proposed method can be readily\napplied to various applications without significant modifications or tuning, as\ndemonstrated by the examples in the paper.\n
