This study studies the problems of stability analysis and stabilisation for networked control systems. The networked control system is modelled as a Markovian jump time-delay system, which is transformed into an interconnected form by the transformation approach. Then, the new stability and the stabilisation conditions are presented based on the scaled small gain theorem and the Lyapunov functional method. The results are much less conservative than other existing results because of the utilisation of the input–output method and some novel techniques. In the illustrated example, the controller of mechanical networked control systems is obtained by the stabilisation condition, which illustrates the less conservatism and effectiveness of the authors’ method.
