PI Controller Design for Networked Control Systems with Random Time Delay

This paper presents an approach to PI controller design for networked control systems(NCSs) with random timedelay. In the proposed approach, the time delay induced by the closed loop over the network is supposed to be bounded, and its upper bound is known. A PI controller is designed for the control of the system with the maximum time delay using a practical approach based on stability region locus. The obtained PI controller is then used to control the actual networked control system. To show the validity and effectiveness of the proposed approach, asimulation example in Matlab/Simulink and TrueTime is given.
