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…

Reducing the LQG Cost with Minimal Communication

This work investigates the optimal trade-off between the improved LQG cost and the consumed communication resources, measured with the conditional directed information, across all encoding-decoding policies and shows that even low-quality measurements can have a significant impact on the required communication resources.

The information causal rate–distortion function with causal decoder side information is defined and it is proved that it bounds from below its operational counterpart.



Control Over Gaussian Channels With and Without Source–Channel Separation

This work implements a separated scheme by leveraging recently developed techniques for control over quantized-feedback channels and for efficient decoding of anytime-reliable codes, and proposes an alternative, namely, to perform analog joint source–channel coding, by this avoiding the digital domain altogether.

Stabilization and Disturbance Attenuation Over a Gaussian Communication Channel

This work considers the problem of stabilizing an unstable system driven by a Gaussian disturbance using a feedback signal transmitted over a memoryless Gaussian communication channel, and shows that for scalar systems the lower bound on the mean square norm of the state is tight, and achievable using linear time invariant communication and control.

Stochastic linear control over a communication channel

It is shown that optimal quadratic cost decomposes into two terms: A full knowledge cost and a sequential rate distortion cost.

Optimization and Tracking of Scalar-Valued LQG Control Under Communication Link with Synchronized or Delayed CaSI at the Decoder

—We consider a closed-loop control problem where a fully observable stochastic linear scalar-valued plant modeled as a time-invariant Gauss-Markov process is connected to a controller via a

A Framework for Control System Design Subject to Average Data-Rate Constraints

This paper develops a framework to deal with average data-rate constraints in a tractable manner that combines ideas from both information and control theories and shows that the proposed class of coding schemes can achieve mean square stability at averageData-rates that are, at most, 1.254 bits per sample away from the absolute minimum rate for stability.

The fundamental tradeoff between the communication rate r bits/sec and the limsup of the expected cost b is studied, and a lower bound on the rate necessary to attain b is shown.

Foundations of Control and Estimation Over Lossy Networks

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.

Elements of Information Theory for Networked Control Systems

This chapter reviews a series of contributions at the intersection of information and control theories, briefly describe applications, sketch mathematical arguments, and illustrate in a tutorial style the main information- theoretic and control-theoretic tools used to derive these results.

Zero-Delay Joint Source-Channel Coding Using Hybrid Digital-Analog Schemes in the Wyner-Ziv Setting

The proposed encoding scheme is based on hybrid digital-analog (HDA) transmission in a zero-delay fashion and results in a better performance than the well-known inverse spiral mapping.
