Compensation-based control for lossy communication networks

In this paper we are concerned with the stability analysis and the design of stabilizing compensation-based control algorithms for networked control systems (NCSs) that exhibit packet dropouts. We propose a new type of model-based dropout compensator, which depends on the local dropout history, and we provide LMI-based conditions for their synthesis. The analysis and design framework includes stochastic models to describe the packet dropout behavior in both the sensor-to-controller and controller-to-actuator channel. Via examples we demonstrate the significantly improved robustness with respect to packet dropouts using the proposed dropout compensator, compared to using the zero strategy and the hold strategy.
