Recent advances in networked control systems

This paper presents a comprehensive overview of the current state of research in the area of networked control systems (NCSs) first. Then two modeling and control methods are introduced for NCSs in details. The first one is a stochastic control method, which investigates the H_infin control problem for NCSs with random network-induced delay. The second one is a switch control method, which focuses on solving the stabilization problem for NCSs in discrete-time domain, where both network-induced delay and packet dropout are taken into account. Illustrative examples are given to demonstrate the effectiveness of the proposed approaches. Finally, this paper concludes with the discussion of possible future development of NCSs from a control perspective.
