A reference-model controller to mitigate the effect of time delay change in a networked control systems
Rida Hudaya1.
Various methodologies have been proposed to improve system performance caused by time delay in the network systems. The purpose of this paper is to present an algorithm for mitigating the effect of time delay varying in a Networked Control Systems (NCSs) using a Reference Model Controller. The proposed method is to supervise and measure the transfer function of plant over the network, the result is used to update the reference-model plant. In this experiment, the reference-model used PID controller. The real plant will be driven by the output of PID Controller over the network. With this method, the output of reference-model plant will not be influenced by the delay time varying on the network. The time delay used in this experiment is 0,8s with time delay varying from 0,4s to 1,6s. This time delay is measured directly from the network used by The MatLab software system which is integrated in the reference-model systems. Fact on the filed shows that for the transfer function of reference-model is updated depends on the quality of plants. The good quality plant does no need to update frequently. So this condition can reduce the load of communication and accelerate the control algorithm.
