Title: On Stealthiness of Zero-dynamics Attacks against Uncertain Nonlinear Systems: A Case Study with Quadruple-tank Process
Presenter: Dr. Gyunghoon Park (joint work with Dr. Chanhwa Lee and Prof. Hyungbo Shim)
From 16th to 20th July, the 23rd International Symposium on Mathematical Theory of Networks and Systems (MTNS) held in Hong Kong. In CDSL, Dr. Gyunghoon Park attended MTNS and presented his recent results on stealthiness of zero-dynamics attacks against uncertain nonlinear systems, with a case study about quadruple-tank process.
In his talk, he briefly described about the attacks on the cyber-physical systems, especially the zero-dynamics attack, and then examined whether zero-dynamics attack strategy is still fatal for nonlinear and uncertain systems or not. First, he designed the nonlinear zero-dynamics attack as the mimicry of the smoothened (nominal) zero-dynamics from the Byrnes-Isidori normal form. Next, he showed the stealthiness and the destructibility of the nonlinear zero-dynamics attack.
The material of this presentation is slightly revised from the final submission, and will be provided in the future journal paper and ArXiv.
