This article investigates the non-parallel distribution compensation issue (N-PDC) of Networked Control Systems (NCSs) under a new event-triggered strategy based on the fuzzy system for a class of nonlinear with appearing the time-varying delays. A unified framework of T-S fuzzy model under the new event-triggered strategy is present, in which \textit{(i)} The observer-based fuzzy controller with the incomplete premise matching is a build-up to obtain the unmeasurable states of the system under study; \textit{(ii)} A designed fuzzy controller has used the same premise such as the observer; and \textit{(iii)} To rationally utilize network resources and elaborately avoid unnecessary continuous monitoring, a new event-triggered mechanism with variable parameter and a sampler considered, respectively. Besides we encounter the nonlinear term with the \textit{Lipschitz condition}. Another derives of this paper introduced the $H_{\infty}$ performances index. Furthermore, in this regard, by taking into account a new \textit{fuzzy Lyapunov-Krasovskii functional} (LKF) in conjunction with free weighting matrices, containing mode-dependent non-integral terms such that the resulting system is stable with the desired performance. Then, the desired observer-based controller is presented in the account of LMI. Finally, an illustrative example is provided to demonstrate the effectiveness and superiority of the proposed method.
