This paper investigates the problem of distributed secure state estimation and control for nonlinearly coupled interconnected cyber physical systems (CPS) under sensor attacks. Distributed schemes consisting of pre-selectors and observers are presented to solve the secure state estimation problem. Then, with the obtained state estimation and following the backstepping design procedure, distributed secure control algorithms are derived. Theoretical analysis shows that, with the proposed distributed secure observers and controllers, not only the state estimation of the CPS under attacks is obtained in a given finite time, but also the state tracking is ensured in a finite time. Finally, the developed algorithms are applied to an islanded micro-grid system as an illustration, verifying the effectiveness of the proposed method | URI: | https://hdl.handle.net/10356/90037 http://hdl.handle.net/10220/49357 |
