MODELLING AND REAL-TIME SIMULATION OF A NETWORKED-CONTROL SYSTEM WITH DISTRIBUTED LOADS
Journal Title: Indian Journal of Computer Science and Engineering - Year 2011, Vol 2, Issue 6
Abstract
This paper discusses a control system model which has four access layer servers connected to several loads via four Controller Area Networks (CANs), and these loads are controlled from those servers or virtual interface machines. The system network involves interconnection of Access Layer Servers (e.g. laptops), Ethernet Controller (which establishes a Local Area Network, LAN), and CAN Controllers. This study can be implemented in the control of industrial processes in a real-time. In this work, the Programmable Logic Device (PLD) of the Ethernet controller which is its intelligent Application Specific Integrated Circuit (ASIC) was replaced with a programmed AT89C55 microcontroller to achieve the same switching logic. This microcontroller was programmed in Assembly Language, and the feedback mechanism was achieved using program. Simulation of the system was carried out in a real-time simulation environment using Proteus software (Proteus version 7.6 Professional), and this confirmed the workability of the model in a real-life situation.
