Abstract :
We consider the control performance of an LQG system with a noisy analog feedback channel between the state-observation and the controller. To bound the performance, we use the sequential rate distortion function and the assumption of equi-memory. We then discuss the trade-offs between control and communication costs and how to relax the equi-memory assumption
