Observer design for wired linear networked control systems using matrix inequalities
نویسندگان
چکیده
We design an observer-protocol pair to asymptotically reconstruct the states of a linear time-invariant (LTI) plant under communication constraints induced by the network. We parameterize a class of observers and protocols, and for a given network transmission interval, we derive sufficient conditions in terms of matrix inequalities for the existence of an observer-protocol pair in the considered class that asymptotically reconstructs the plant states. © 2008 Elsevier Ltd.

Design 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 کاملModelling and Compensation of uncertain time-delays in networked control systems with plant uncertainty using an Improved RMPC Method
Control systems with digital communication between sensors, controllers and actuators are called as Networked Control Systems (NCSs). In general, NCSs encounter with some problems such as packet dropouts and network induced delays. When plant uncertainty is added to the aforementioned problems, the design of the robust controller that is able to guarantee the stability, becomes more complex. In...
متن کاملObserver-based networked control for continuous-time systems with random sensor delays
This paper is concerned with the networked control system design for continuoustime systems with random measurement, where the measurement channel is assumed to subject to random sensor-delay. A design scheme for the observer-based output feedback controller is proposed to render the closed-loop networked system exponentially mean-square stable with H∞ performance requirement. The technique emp...
متن کاملOutput-Feedback Control for Networked Systems with Probabilistic Delays
The networked control system (NCS) design for continuoustime systems with probabilistic delays is discussed in this paper. The delay is assumed to follow a given probability density function. A design scheme for the observer-based output feedback controller is proposed to render the closedloop networked system exponentially mean-square stable with H∞ performance requirement. The design method i...
متن کاملStabilization 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...
