Time delay uncertainty among the sensors, actuators and controllers is a key problem for the networked control system (NCS). After analyzing the time delay characteristic of a networked AGC system, a robust AGC controller is presented in this paper to meet the networked time-delayed environment by using the time-delayed system control theory. The time-dependent stability criteria is adopted to design the robust H∞ controller. It can overcome the conserativeness which is brought by the time-independent stability criteria,moreover,the coefficient in the state equations need not meet any constraint.A two-area AGC system is studied through digital simulations, to demonstrate the comprehensive applications of the proposed strategy, and the result shows the effectiveness of the presented strategy.
