“…They have been around for some decades already, and they have been implemented successfully in many fields such as industrial automation, robotics, and power grids. Although the NCSs provide several advantages to the systems, it is well-known that one of the problems is the system performance degradation caused by the data rate constraints in the communication channels [1][2][3]. In the case that operation signals of NCSs are transmitted over networks under data rate constraints, the signal quantization is a fundamental process in which a continuous-valued signal is transformed into a discrete-valued one.…”

Hybrid-Driven-Based H∞ Control for Offshore Steel Jacket Platforms in Network Environments

“…It should be mentioned that network control systems (NCSs) have some practical advantages such as plug and play equipment and low maintenance cost, and have received a great deal of attention, see [15]- [21]. Compared with the traditional point-to-point control, the network-based control strategy is more effective and feasible for an offshore platform.…”

A Time-Delay-Bounded Data Scheduling Algorithm for Delay Reduction in Distributed Networked Control Systems

“…In practical NCSs, there exist numerous information sources and nodes exchanging data over the networks simultaneously, and thus, the time delays induced by network resource sharing would generate inevitably [3][4][5]. Such time delays could largely degrade the system performances or sometimes may even cause the system to be instable.…”

“…Furthermore, as the time delays within NCSs could either be constant, or bounded, or random, they also make the NCS system design and analysis complicated. erefore, it is of critical importance to reduce the NCS time delays in engineering practice [5,6].…”
