On Optimal System Design for Feedback Control Over Noisy Channels

The authors study a closed-loop multivariable control system with sensor feedback transmitted over a discrete noisy channel. For this problem, they propose a joint design of the state measurement quantization, protection against channel errors, and control. The proposed algorithm leads to a practically feasible design of time-varying non-uniform encoding and control. Numerical results demonstrate the performance obtained by employing the proposed iterative optimization algorithm. In recent years, the demand for sharing resources efficiently in large networked systems has been continuously increasing. However, in many situations, there is a challenging conflict between the amount of transmitted data and the response time.
