“…Sometimes, all the data packets containing the plant measurements may not be permitted to be transmitted because of limited bandwidth, which may deteriorate the system performance and stability. The problem of stabilization with finite communication bandwidth was introduced in [42] and further dealt with in [43]. A new framework for distributed control systems was introduced in [44], which used estimators at each node to achieve significant savings in the required bandwidth.…”

The insertion of the communication network in the feedback control loop makes the analysis and design of a network control system more complex, and induces some issues that degrade the control system's performance and even cause system instability. The main aspects are focused on the stability analysis of Network Control Systems (NCSs) with network-induced delays, data packet dropouts, and multiple-packet transmission. These issues must be considered in the design of an NCS. This work summarizes the main research results, and remarks on some related handling approaches and techniques. The main purpose of the survey is to present the new research state of NCSs and to point out some fields of future work.

“…The communication bus select a transmitting signal by periodic pattern, so that the NCS is described as a periodic system. This model was first proposed by Brockett [3] and Hristu presents a solution of this problem based on the simulated annealing [5]. Shinmyo et al proposed different algorithm and obtained a better result [6].…”

In this paper, we show the design method of the networked control system with structured uncertainty. In this system, the plant and the controller are connected with a communication bus. The plant and controller are denoted as LTI-system, but the communication bus has a periodic characteristic. So that the whole of the system characteristics is denoted as a periodic system. In this paper, we consider the guaranteed cost control in the case with the linear time-varying system. As this result, we derive the stochastic discrete algebraic Riccati equation of the time-varying case and apply this equation to the design problem of networked control system. In the numerical example, the plant is car-pendulum system with uncertainty. Through the numerical result, we show the effectiveness of our proposed method.

“…For example, it is well known that in a broadcast network, only one communication channel is provided and thus only one node is allowed to transmit packets to another node at each transmission instant. In this paper we call this issue as the communication constraint in networked systems, keeping the terminology used in [1,2,8]. Moreover, in networked systems data has to be quantized before transmission, and packets may be lost during transmission due to the unreliability of the networks.…”

“…Up to now, the control problem of networked systems has received extensive research attention, see for example, [1][2][3]7,8,11,14,15,[23][24][25]29], and the references therein. On the other hand, the filtering problem of networked systems also receives increasing attention [7].…”
