Throughput-Maximum Energy-Aware Rate Adaptation in W-NCSs over Quasi-Static Fading Channels

In this paper, we consider a wireless networked control system (W-NCS) and seek to optimize the performance of the system by adapting the transmission throughput of the communication link, which is assumed to be a quasi-static fading channel. Towards this end, an optimization problem is formulated and solved, herein called Maximum Throughput with Energy Constraints (MaxTEC), in which the optimal achievable throughput is selected subject to the limited available energy per transmission. It is demonstrated that the larger the available energy, the higher the throughput, and, subsequently, the better the control performance. The performance of our proposed scheme is illustrated via simulations of an inverted pendulum on a cart
