Stability Analysis of Networked Predictive Control Systems with Random Network Delay

The paper is concerned with the design and stability analysis of networked control systems with random network delay, which are described in a state-space form. It presents a new control scheme, which is termed networked predictive control. This scheme mainly consists of the control prediction generator and network delay compensator. The control prediction generator provides a set of future control predictions to make the closed-loop system achieve the desired control performance and the network delay compensator removes the effects of the network transmission delay. The stability criteria of the closed-loop networked predictive control systems are analytically derived for fixed. In case of random network delay, a switched system´s method has been proposed, which solves the stochastic problem in a deterministic way.
