This study presents a two-level Quasi T-S fuzzy (QTS) model to represent nonlinear networked control systems (NCS), which takes the performance of network with time-delay and data packet dropouts into the investigations. At the working points of nonlinear NCS, regard the subsystem as linear system modelling by QTS, then the global model of nonlinear is fuzzy fused by linear subsystem. This study constructs the corresponding system model, in which the system's stability is proved with linear matrix inequality (LMI). As a bench test a nonlinear system is selected to demonstrate the feasibility and efficiency though numerical analysis. This study provides a new method of fault diagnosis and tolerance control of nonlinear NCS.
