Finite‐Time‐Based Dissipative State Estimation for Discrete‐Time Conic‐Type Nonlinear Systems With Packet Dropouts Under Round Robin Protocol

ABSTRACT This article explores the finite‐time‐based state estimation problem of discrete‐time conic‐type nonlinear systems subject to packet dropouts under round robin protocol (RRP). To avoid data collisions and save network resources, the RRP is implemented to coordinate the simultaneous transmission of signals from the sensor nodes of a fixed circular order, which greatly reduces the total amount of data sent at each time instant. The resilient filter strategy is proposed by taking the effects of the filter gain variations and packet dropouts into account. Then, based on the augmented system model, an adequate condition is attained. Moreover, the resilient filter parameter is obtained such that the conic‐type nonlinear systems reach finite‐time bounded with strictly dissipative. Ultimately, the efficacy of the developed estimator is demonstrated through two numerical simulations.
