Decentralized Stabilization of Networked Systems under Data-rate Constraints

چکیده
The paper deals with an advanced networking scenario involving a noisy linear plant with multiple actuators and sensors connected via a complex communication network with varying topology. The network contains a large number of spatially distributed nodes equipped with CPU’s that process and transmit data. Processing algorithms need to be designed for some nodes, whereas they are fixed for other nodes. During transmission, data may incur delays, be lost or corrupted. The objective is to stabilize the plant. A necessary and sufficient condition for stabilizability is given in terms of the so-called rate (capacity) domain of a communication network. It is shown that the problem of networked stabilization of noisy plants is ultimately reduced to a hard long-standing one of the information theory: calculating the capacity domains of communication networks.

Stabilization of Networked Control Systems with Variable Delays and Saturating Inputs
In this paper, improved conditions for the synthesis of static state-feedback controller are derived to stabilize networked control systems (NCSs) subject to actuator saturation. Both of the data packet latency and dropout which deteriorate the performance of the closed-loop system are considered in the NCS model via variable delays. Two different techniques are employed to incorporate actuator...

The application of Networked Control Systems (NCS) in which sensory and control signals are transmitted via shared data communication networks, is growing significantly and these systems have been the subject of research during the last decade. On the other hand, multirate sampled data systems have been investigated since a long time. In this paper, conditions under which a networked control sy...
متن کاملDesign of Observer-based H∞ Controller for Robust Stabilization of Networked Systems Using Switched Lyapunov Functions
In this paper, H∞ controller is synthesized for networked systems subject to random transmission delays with known upper bound and different occurrence probabilities in the both of feedback (sensor to controller) and forward (controller to actuator) channels. A remote observer is employed to improve the performance of the system by computing non-delayed estimates of the sates. The closed-loop s...
متن کاملQuantized Feedback Control for Networked Control Systems Under Communication Constraints
This paper investigates the feedback stabilization problem for networked control systems (NCSs) with unbound process noise, where sensors and controllers are connected via noiseless digital channels carrying a finite number of bits per unit time. A sufficient condition for stabilization of NCSs, which relies on a variable-rate digital link used to transmit state measurements, is derived. A lowe...
