Intelligent scheduling and optimisation for resource-constrained networks

Sensor scheduling strategies for fault isolation in networked control system

“…Few methods have been proposed in the literature to reduce the complexity of such an approach. One can see [15,16,27] and the references therein. In the present paper, we will consider an infinite-horizon scheduling problem.…”

Dynamic Intelligent Feedback Scheduling in Networked Control Systems

“…Until now, there are various scheduling methodologies for NCS with limited bandwidth resources [9][10][11][12][13][14][15][16][17][18][19][20]. The static scheduling strategies are traditionally employed as bandwidth scheduling techniques, as reported in [9][10][11][12] and the references therein.…”

“…In recent years, researches on dynamic scheduling of NCS have received a great deal of attention and many results have been reported; see examples in [13][14][15][16][17][18][19]. In these dynamic scheduling strategies, the bandwidth resources are dynamically allocated by adjusting the sampling periods of control loops in runtime, so that the system can sufficiently utilize the sharing resources and effectively improve the overall control performance.…”

“…In [14], considering single optimal objective of control performance subject to available bandwidth constraints, an optimal bandwidth allocation strategy based on linear programming technique was proposed. In [15], two intelligent and optimal scheduling strategies, based on fuzzy logic and neural network techniques, respectively, were employed for optimal bandwidth scheduling in multiloop NCS. Moreover, in [16], a network monitor was introduced to obtain the current network bandwidth and network-induced transfer error; subsequently, the sampling period of each control loop was dynamically regulated in terms of the estimated available network resources and network-induced error.…”

Control with sensors/actuators assigned by Markov chains: transition rates partially unknown

“…The concept of communication sequence was introduced to define the schedule of sensors/actuators, see Brockett [4] and Rehbinder and Sanfridson [5]. Recently, attention has been paid to online co-design of controller and communication sequence, see, for example, in Zhang and Hristu-Varsakelis [6,7], Guo [8] and Longo et al [9], and to bandwidth assignment for sensors/actuators in NCSs, see, for example, in Zhao et al [10] and Li et al [11]. These works are restricted to either offline static scheduling or dynamic scheduling.…”
