This paper addresses event-triggered H filtering for networked Takagi–Sugeno fuzzy systems with the asynchronous constraints of the membership functions. First, an event-triggered communication (ETC) scheme is proposed to trigger the transmission only when the variation of the sampled vector exceeds a prescribed threshold condition. Second, a model of fuzzy filtering error system is built under consideration of the ETC scheme, asynchronous premise and communication delay in a unified framework. Then, less conservative criteria on H filtering analysis and design are derived by making use of the re-constructed asynchronous premises. Finally, two examples are used to show the effectiveness of the proposed method.
