In this research, we provide a co-design strategy for WNCS that simultaneously optimizes network and control parameters. The goal is to optimize power use on the wireless communication layer by establishing a variable inter-packet gap (IPG) or by transforming the control strategy from reliable control to energy-efficient control with moderate reliability. Control performance is optimized for moderate to high packet loss using an RL-based technique that guarantees optimal resource allocation. The design of a multi-objective issue that takes into account both dependability and resource efficiency makes this possible. The developed approach is then applied to the multi-objective optimization problem. The suggested co-design RL-based control approach shows the ability to reduce transmission power by an average of 5% to 10% even when there are losses in the network. In addition, it effectively preserves or enhances control performance.
