This paper discusses the fuzzy adaptive consensus secure control problem for a class of stochastic nonlinear multi-agent systems (MASs) with unknown false data injection attacks. Fuzzy logic (FLSs) are used to model functions. A distributed filter is proposed obtain information leader since leaders only available partial agents. To deal virtual time-varying gains caused by attacks, an compensation method developed via re-codesigning controllers. Based on backstepping methodology and bounded...

As a generation of the real-valued neural network (RVNN), complex-valued (CVNN) is based on (CV) parameters and variables. The fractional-order (FO) CVNN with linear impulses fixed time delays discussed. By using sign function, Banach point theorem, two classes activation functions, some criteria uniform stability for solution existence uniqueness equilibrium are derived. Finally, three experimental simulations presented to illustrate correctness effectiveness obtained results.
