This paper investigates the problem of finite-time dynamic output feedback (DOF) control for fuzzy networked discrete-time systems. By constructing a generalized performance index, the H control and l2l control problems are accessed under a unified framework. An adaptive event-triggered scheme (AETS) and a logarithmic quantizer are utilized to save the limited network bandwidth. Based on the Lyapunov function approach, sufficient conditions are proposed to guarantee the closed-loop system being finite-time bounded with the prescribed performance index, and the design criterion of the finite-time DOF controller is given by an exact expression. Finally, a simulation study is performed to illustrate the effectiveness of the developed method.
