Control synthesis problem for networked linear sampled-data control systems with band-limited channels

This paper addresses the control synthesis problem of networked linear sampled-data control systems (NLSCSs) with band-limited channels. First, since there exist packet dropouts when the information is transmitted through the band-limited channels, a novel compression compensation (C–C) method is proposed to ensure the integrity of transmission. Based on this method, a compound control strategy is established to deal with the data transmission synchronization problem under the band-limited channels. Then, a nonlinear switched system model with uncertainty is constructed, in which both the inter-sampler behavior and the packet dropouts behavior are considered. Furthermore, some more general stability results of the NLSCSs with band-limited channels are obtained by using a packet dropouts dependent Lyapunov functional method, and then the compound state feedback controller can be designed. Finally, an illustrative example is given to demonstrate the effectiveness of the proposed results.
