| Abstract | ||||
| Networks and their applications have been evolving substantially in the last two decades. Networked Control Systems (NCS) are one of the hottest topics in network-based applications. By networked control system we mean controlling the system through the network. Such systems offer advantages such as lower installation costs, increased flexibility, reliability, also reduced maintenance costs. The change of communication architecture from point-to-point to this common bus approach, however, introduces different forms of loss of packets in the closed-loop system dynamics. These packets loss comes from node failures or message collisions. Packet losse in a control application can degrade a system's performance and even cause system instability. In this paper, optimal design of fuzzy logic PI and PID controllers have are developed to compensate the network-induced packet losses. Simulink model of a distributed DC servo system using CAN network has been built. Different simulation examples are given to explore the simplicity and effectiveness of the proposed controllers in compensation of the packet losses compared with other different techniques. | ||||
