Necessary and Sufficient Condition of Optimal Control for Networked Control Systems with Markovian Packet Dropouts

Channel Switching Algorithms for a Robust Networked Control System with a Delay and Packet Errors

“…LQG control was developed under the framework of Markovian jump linear systems [12], and under the separation principle when perfect information on the acknowledgment of the control input was available [13]. A necessary and sufficient condition for the optimal control for minimizing the control cost was given as a positive definition condition of a matrix [14]. A heuristic predictive control [15] and a novel compensator [16] were also proposed to provide the stabilization of NCS for different channel conditions.…”

“…Numerous contemporary devices provide users with a plethora of network access options, exemplified by the seamless transition between 4G and 5G networks or 5G and Wi-Fi networks on smartphones. However, existing research, to the best of the author's knowledge, predominantly assumes the simultaneous availability of information from multiple channels, even considering potential data loss due to packet errors [7][8][9][10][11][12][13][14][15][16]. It is important to note that the majority of control systems and devices traditionally accommodate only a single connection at any given time.…”
