Stability analysis of networked control systems with quantized feedback

This paper discusses the stability of linear networked control systems (NCSs) which considers the effects of both network-induced delay and signals quantization. Then, a sufficient condition for the stability is presented by using the Lyapunov functional approach. By solving linear matrix inequalities (LMIs), state feedback gain matrix can be obtained. A numerical example is used to illustrate the effectiveness of the proposed method.
