# Schemes for LQG Control over Gaussian Channels with Side Information

@article{Lev2021SchemesFL, title={Schemes for LQG Control over Gaussian Channels with Side Information}, author={Omri Lev and Anatoly Khina}, journal={2021 XVII International Symposium "Problems of Redundancy in Information and Control Systems" (REDUNDANCY)}, year={2021}, pages={85-90} }

We consider the problem of controlling an unstable scalar linear plant over a power-constrained additive white Gaussian noise (AWGN) channel, where the controller/receiver has access to an additional noisy measurement of the state of the control system. To that end, we view the noisy measurement as side information and recast the problem to that of joint source–channel coding with side information at the receiver. We argue that judicious modulo-based schemes improve over their linear…

This paper considers control and estimation problems where the sensor signals and the actuator signals are transmitted to various subsystems over a network and shows that for network protocols where successful transmissions of packets is acknowledged at the receiver, there exists a critical threshold of network reliability below which the optimal controller fails to stabilize the system.
