Stabilization of a networked control system under bounded disturbances with unreliable communication links via common Lyapunov function approach

Abstract

This paper proposes a design method for stabilization of a networked control system with bounded disturbances and unreliable links. In such a communication link, data loss often occurs and may deteriorate control performance. In our approach, the last control signal is reused when data to be received is lost. This mechanism is a kind of switched system. Therefore, a design technique for switched systems can be applied to design problem of the networked control system. In numerical examples, the effectiveness of our approach is illustrated.
