Abstract	This paper proposes a novel improved adaptive event-triggered control algorithm for networked Takagi-Sugeno (TS) fuzzy systems with asynchronous constraints. Firstly, taking the limited bandwidth of network into consideration, an improved adaptive event-triggered mechanism is proposed to save the communication resource. Superior to the existing event-triggered mechanism, the improved adaptive event-triggered scheme introduces two adjusting parameters, which further contribute to the economization of the communication resource. Secondly, with consideration of asynchronous premise variables, a reconstructed approach is applied to synchronize the time scales of membership functions of the fuzzy system and the fuzzy controller. Thirdly, to derive a less conservative sufficient condition for controller design, a new augumented Lyapunov-Krasovskii functional with event-triggered information and triple integral terms is constructed. Meanwhile, by applying a Bessel-Legendre inequality and extended reciprocally convex matrix inequality together, a new control algorithm is derived with less conservatism. Finally, simulations on a cart-damper-spring system are implemented to evaluate and verify the performance and advantages of the proposed algorithm.
