Data Transmission Over Networks for Estimation and Control

Abstract: Abstract-We consider the problem of controlling a linear time invariant process when the controller is located at a location remote from where the sensor measurements are being generated. The communication from the sensor to the controller is supported by a communication network with arbitrary topology composed of analog erasure channels. Using a separation principle, we prove that the optimal linear-quadratic-Gaussian (LQG) controller consists of an LQ optimal regulator along with an estimator that estimates … Show more

“…However, the presence of a network within the control loop can adversely affect the performance of the system due to the inherent unreliability (e.g., packet drops or transmission latency) of the communication channel. Such anomalies have direct consequences on the stability of the plant, as shown in previous studies [1,2,7,8,11,17,19].…”

“…We assume that the system is designed in such a way that stability (in an appropriate sense) is attained despite the presence of packet drops (e.g., if the conditions provided in works such as [7,9,15,24], etc. are satisfied).…”

“…On the other hand, the study of time-delay and packet-dropouts mainly focuses on periodic transmission schemes [8,19] or on finding upper bounds on the sampling period [10]. In [18] the design of optimal level-triggered impulse control under packet dropouts with multiple loops sharing a common network is considered.…”
