Abstract: In this paper, a novel controller is proposed for Networked Control Systems (NCSs) with random delays and non-linearity using BP neural networks and Fisher information. The controller is designed by minimising the Fisher information of tracking error. The Fisher information is calculated based on estimated Probability Density Function (PDF) via the Parzen windowing technique. The convergent condition of the proposed control algorithm is given. A simulation example is given to show the effectiveness of the proposed algorithm.

Keywords: NCS; networked control systems; neural networks; neuro PID controller design; random delays; Fisher information; tracking errors; simulation.
