摘      要：In this paper, the hybrid-triggered control (HTC) problem for nonlinear networked control systems with external disturbance is investigated by employing Takagi-Sugeno (T-S) fuzzy model. First of all, the observers are constructed to estimate system state and disturbance, respectively. With the help of disturbance estimation and attenuation (DEA) technique, the influence of external disturbance is attenuated effectively. Next, the HTC strategy is proposed to save the limited network resource while maintaining the desirable system performance. Then sufficient condition is proposed to ensure the exponential stability of the resultant closed-loop system, and the observer-based fuzzy controller is designed by solving an optimization problem. Finally, the effectiveness of the developed method is verified by a practical example.
