摘要：
To alleviate the pressure of network data transmission, the output feedback H∞ controller design problem is investigated for a class of saturated 2-D systems described by the Roesser model under the dynamic event-triggered mechanism. First, the mathematical model of such an uncertain saturated 2-D system is developed. Second, in order to reduce the update frequency of the signal, a dynamic event-triggered mechanism is proposed to determine whether the current information can be transmitted to the network. Based on the Lyapunov function method, a sufficient condition is given to ensure that the corresponding closed-loop system meets the certain H∞ performance index, and the existence criterion for the output feedback controller is obtained by introducing a non-negative scalar µ. Moreover, with the aid of the cone complement linearization algorithm, the design problem of the output feedback controller can further be transformed into a nonlinear minimization problem constrained by linear matrix inequalities. Finally, the numerical simulation is presented to verify the effectiveness and feasibility of the output feedback control scheme. © 2024 Northeast University. All rights reserved.
