“…Suppose that the system described by (18) and (19) is stabilizable, which is a basic assumption in this work as mentioned previously in Section 2.1. The feedback gain K in (5) is designed in advance such that b A ¼ A þ BK is stable and kCðSI À b AÞ À1 B 1 k 1 < c, where c is given in Definition 2.…”

“…Lee et al investigated the location encoding method for moving objects using road network [11]. Wong et al studied the route optimization in mobile IP networks [18]. Regardless of these recent developments, limited work has been found in the open literature on robust H 1 control design with consideration of both network conditions and signal quantization.…”

This paper addresses the problem of H 1 controller design for linear systems over digital communication networks. A new model is proposed to describe both the network conditions and the state quantization of the networked control systems in a unified framework. From this model, a quantized state feedback strategy is developed for global and asymptotical stabilization of the networked control systems. The same H 1 disturbance attenuation level as that in the case without quantization is achieved. Numerical examples are given to demonstrate the effectiveness of the proposed method.

“…For general mobile IP networks, Wong et al [32] investigated the impact of route optimization on out-of-order packet delivery. They proposed an analytical model to assist in this investigation, and further analysed how the transmission delay distributions affect the probability of the out-of-order delivery.…”

With the integration of communication networks and distributed control in modern manufacturing and process industries, networked control systems (NCSs) are becoming increasingly important due to its simplicity, scalability, flexibility, and cost effectiveness. However, there are still significant technical barriers that limit the applications of NCS technologies. Two challenges are network-induced time delay and data packet dropout. Applying a real-time queuing protocol that we developed recently, we are able to limit the sum of the network-induced communication delay and the control computation delay within a control period. This one-period delay is further guaranteed by well designed compensation for control packet dropout. Then, this paper proposes to compensate for the control packet dropout at the actuator using past control signals. Three model-free strategies for control packet dropout compensation, namely, PD (proportional plus derivative), PD2 (proportional plus up to the second-order derivative), and PD3 (proportional plus up to the third-order derivative) are developed. They are suitable for a large number of NCSs without the need to tune the compensator parameters. The proposed dropout compensation schemes are demonstrated through numerical examples.

“…It is worth noting that Mobile IPv4 does not implement the route optimization concept, which may cause a disruption of packet sequences during packet delivery, which in turn may result in degradation of the performance of mobile TCP/IP. Wong et al [37] investigated the impact of route optimization on out-of-order packets in Mobile IPv4 networks.…”
