Finite-time control of networked stochastic systems with disturbances and false data injection attacks

In this paper, networked stochastic systems (NSSs) subjected to disturbances and false data injection attacks (FDIAs) is studied, which have been extensively utilized in practical engineering. To fully utilize the disturbance information, a stochastic disturbance observer (SDO) is introduced to estimate the exogenous disturbance; since the state of the system is often unavailable under the FDIAs, an output observer is designed to obtain the estimation of the state. On these basis, the finite-time controller is constructed to compensate the disturbance and attenuate the FDIAs simultaneously, which can ensure the stability of the systems, and the convergence time can be restricted to a certain period of time. Finally, the effectiveness of the proposed scheme is verified by simulations.
