“…Since then, control theorists and control practitioners have remained highly active in this research area, such as by combining control and information theories [ 6 , 7 ] or linear optimal control and communication theory; examples include [ 8 , 9 , 10 ]. The last few years have also seen an increase in event-triggered NCS solutions [ 11 , 12 , 13 ], that is, asynchronous control closed-loop solutions, which aim to increase the efficiency of specifically limited communication resources while achieving a set of given objectives (stability, performance, robustness, or a combination of these). These and other NCS results are the foundation of better control.…”

In this work, we consider the design of power-constrained networked control systems (NCSs) and a differential entropy-based fault-detection mechanism. For the NCS design of the control loop, we consider faults in the plant gain and unstable plant pole locations, either due to natural causes or malicious intent. Since the power-constrained approach utilized in the NCS design is a stationary approach, we then discuss the finite-time approximation of the power constraints for the relevant control loop signals. The network under study is formed by two additive white Gaussian noise (AWGN) channels located on the direct and feedback paths of the closed control loop. The finite-time approximation of the controller output signal allows us to estimate its differential entropy, which is used in our proposed fault-detection mechanism. After fault detection, we propose a fault-identification mechanism that is capable of correctly discriminating faults. Finally, we discuss the extension of the contributions developed here to future research directions, such as fault recovery and control resilience.

“…In recent years, the event‐triggered scheme has attracted growing interest and attention in control systems [1, 2]. As an alternative to the traditional time‐triggered scenario, the advantage of this scheme is that the communication burden could be alleviated without sacrificing system performance largely [3, 4].…”
