State Predication Control of Discrete Networked Control Systems

The paper presents a state predication controller design method to compensate time-delay in discrete networked control systems (NCS). We apply multi-step prediction to current state of the system based on the object prediction model and the measured state values to compensate the stochastic time-delay of NCS. Furthermore, with respect to the case of networked inducing delay and data package loss, the presented method can improve the performance of NCS too. At last, the simulation results validate the given design method.
