Grey Prediction Control in the Application of Networked Control Systems

Focusing on the influence made by the time-delay of networked control systems to the system performance and the problems that we are unable to obtain controlled object with all state information in industrial field, a new algorithm to compensate the bad effect caused by the network time-delay is proposed based on the grey prediction method to predict the output of the controlled object at future time. Finally simulate the algorithm by using the TRUETIME toolbox. The result demonstrates that the compensatory strategy in this paper can improve the system performance.
