Pilot-Free Optimal Control over Wireless Networks: A Control-Aided Channel Prediction Approach
Minjie Tang, Zunqi Li, Photios A. Stavrou +1
A recurring theme in optimal controller design for wireless networked control systems (WNCS) is the reliance on real-time channel state information (CSI). However, acquiring accura…
Multi-Sensor Scheduling for Remote State Estimation over Wireless MIMO Fading Channels with Semantic Over-the-Air Aggregation
Minjie Tang, Photios A. Stavrou, Marios Kountouris
In this work, we study multi-sensor scheduling for remote state estimation over wireless multiple-input multiple-output (MIMO) fading channels using a novel semantic over-the-air (…
Rollout-Based Approximate Dynamic Programming for MDPs with Information-Theoretic Constraints
Zixuan He, Charalambos D. Charalambous, Photios A. Stavrou
This paper studies a finite-horizon Markov decision problem with information-theoretic constraints, where the goal is to minimize directed information from the controlled source pr…
CSI-Free Low-Complexity Remote State Estimation over Wireless MIMO Fading Channels using Semantic Analog Aggregation
Minjie Tang, Photios A. Stavrou, Marios Kountouris
In this work, we investigate low-complexity remote system state estimation over wireless multiple-input-multiple-output (MIMO) channels without requiring prior knowledge of channel…
Sequential Source Coding for Stochastic Systems Subject to Finite Rate Constraints
Photios A. Stavrou, Mikael Skoglund, Takashi Tanaka
In this paper, we revisit the sequential source coding framework to analyze fundamental performance limitations of discrete-time stochastic control systems subject to feedback data…
The Effect of Time Delay on the Average Data Rate and Performance in Networked Control Systems
M. Barforooshan, M. S. Derpich, P. A. Stavrou +1
This paper studies the performance of a feedback control loop closed via an error-free digital communication channel with transmission delay. The system comprises a discrete-time n…
