Resilient set-membership state estimation for nonlinear complex networks with time-delay and incomplete measurements

Taking the incomplete measurements and weighted try-once-discard (WTOD) protocol into account, this paper develops a novel resilient set-membership state estimation (RSMSE) method for time-varying nonlinear complex networks with time-invariant delay. A classic interval matrix technique is utilized to describe measurements. The Taylor series expansion applied dispose nonlinearities, where high-order terms of linearization errors are described by norm-bounded uncertainties. To mitigate communication burden, WTOD introduced, only one node can send updated data through shared network at each certain transmission step. Using recursive linear inequalities (RLMIs), ellipsoidal sets including vector be determined. desirable estimator gain smallest possible ellipsoid calculated via solving convex optimization problem. Lastly, we use an illustrative example show feasibility introduced RSMSE technique.
