This paper investigates the H∞ stability analysis ofnetwork-based cascade control systems against networked delay.Based on the Finsler lemma and the Lyapanov function, thestability criteria are derived by designing a static outputfeedback(SOF) controller with the help of linear matrixinequalities (LMIs). A simulation example is given to show theperformance of the proposed control structure.
