One-step receding horizon control for networked control systems with random delay and packet disordering

Adaptive sampling rate control for networked systems based on statistical characteristics of packet disordering

“…So far, the majority of NCSs research efforts have focused on controller design to provide sufficient stability conditions in the presence of packet disordering [5][6][7][8][9][10]. Significant works have also been reported on how to describe packet disordering, such as comparing the sampling instants of received signals [5], identifying packet disordering by displacements of packets [6,7], and comparing transmission delay [8].…”

“…Significant works have also been reported on how to describe packet disordering, such as comparing the sampling instants of received signals [5], identifying packet disordering by displacements of packets [6,7], and comparing transmission delay [8]. Based on those, a so-called active compensation scheme, wherein late packets are discarded, has been used in [6][7][8][9][10]. In the sense of stabilizing the NCSs, this type of methodology is effective.…”

“…The measurement studies done by [3,[11][12][13][14] showed the impact of packet disordering on end-to-end application performances and predicted the increasing trend of out-of-order deliveries. It should be pointed out that heavy packet disordering would bring challenges for the methods in [6][7][8][9][10] wherein the degree of packet disordering is ignored. The other is that statistical characteristics shown by packet disordering have not been analyzed in the aforementioned literature so far, such that the existing methods are either highly inefficient or not optimal in real networked control system applications.…”

Bilateral Control System of Nonlinear Flexible Master-Slave Arms with Random Delay Using Extended Kalman Filter

“…Wu et al and Guo et al investigated the mean square exponentially stability for the network system with the long random delay and a type of discrete-time system with random delay [1], [2]. Liu et al studied the model predictive control problem for the networked system which cause the random delay defined as a Markov chain [3]. Schenato researched to design the optimal estimator.…”

Bilateral Control System of Flexible Master-Slave Arms with Random Delay Using Kalman Filter

“…Liu et al investigated the model predictive control problem for closed-loop networked control systems. In this study, a random delay is defined as a Markov chain, and then the closed-loop networked control system is expressed as a Markovian jump system [6]. Wu et al proved the mean-square exponential stability for a networked system with long random delay [7], and Guo et al studied exponential stability (in the mean-square sense) for a type of discrete-time system with random delay [8].…”
