Data Transmission over Networks for Estimation
In this paper, we consider the following problem. Suppose a sensor is taking measurements of a dynamic process. It needs to communicate the information to an estimator over a network of communication links that can drop packets stochastically. What is the optimal processing at each node in the network that allows the estimator to estimate the state of the process? We provide a strategy that yie...
متن کاملRedundant data transmission in control/estimation over lossy networks
In lossy networks the probability of successful communication can be significantly increased by transmitting multiple copies of a same message through independent channels. In this paper we show that communication protocols that exploit this by dynamically assigning the number of transmitted copies of the same data can significantly improve the control performance in a networked control system ...
متن کاملRedundant Data Transmission in Control/Estimation Over Wireless Networks: Extended Version
In wireless networks the probability of successful communication can be significantly increased by transmitting multiple copies of a same packet. Communication protocols that exploit this by dynamically assigning the number of transmitted copies of the same data can significantly improve the control performance in a networked control system with only a modest increase in the total number of tra...
متن کاملEstimation and Control over Lossy Networks
Motivated by control applications over lossy packet networks, this paper considers the Linear Quadratic Gaussian (LQG) optimal control problem in the discrete time setting and when packet losses may occur between the sensors and the estimation-control unit and between the latter and the actuation points. Previous work [1] shows that, for protocols where packets are acknowledged at the receiver ...
متن کاملLecture Summary: Estimation and Control over Networks
Motivation: To fully solve the networked control problem, problems that involve multiple sensors, communication channels, controllers and processes need to be considered. We briefly review the known results for the analog erasure channel and the digital noiseless channel models when (i) multiple sensors observe the same process and transmit information to the controller, and (ii) the sensor tra...
