Real-time on-line fuzzy logic simulation system

Computer application technology is increasing in all sectors of industry and commerce. For this reason it is considered essential that today's students are conversant with the concepts and benefits of computer technology. This fuzzy logic simulation project is aimed at providing a student environment where these concepts can be easily and effectively taught, and to provide practical solutions to real industrial problems. This paper describes the development of such a system. A fuzzy logic system is modeled, analysed and tested in an industrial environment. This involves the application of the software toot MATLAB to generate a mathematical model of a system and compare fuzzy logic algorithms with that of traditional control system design. Once the mathematical model was tested with a graphical simulation package, the system can then be implemented in a real-time environment. This allows any necessary changes to be made without interfering with the output of the system. The aimis to use such a system to broaden the available media for teaching and understanding fuzzy logic and as a consequence allow students to learn not only fuzzy logic, but control systems in a new and exciting manner, previously unavailable to them. Omron Electronics, Landis & Stacfa, The Mathworks Inc., Auckland Institute of Technology and the University of Auckland are presently supporting this project.
