Leveraging Retransmissions in Wireless Networked Control Systems with Packetized Predictive Control

In this work we propose a communication and control joint design strategy using packetized predictive control and halted Chase combining hybrid automatic repeat request to minimize the bandwidth required to provide ultra-reliable low latency communications towards wireless networked control systems. The joint design nature comes from tunning at the same time both the length of the control horizon, a control parameter, and the maximum number of transmission attempts, a communication variable. Numerical results show that by using this strategy and correctly choosing the parameters, significant savings in bandwidth can be achieved
