Robust filtering for multirate nonlinear networked control systems

In this paper, the filtering problem is studied for a class of networked multirate nonlinear systems, where not only the network-induced delays but also the packet dropouts are considered. The objective is to design the corresponding filter to guarantee that the estimation errors under the effect of stochastic disturbance are bounded. The filter is designed via the idea that the associated multirate nonlinear system can be expressed as the nonlinear system with mixed delays. Finally, the simulation study of continuous stirred tank reactor (CSTR) system in double-layer architecture further demonstrates the proposed method.
