A demonstration system based on a fuzzy logic controller

Abstract

In the semiconductor manufacturing industry, many systems to be controlled are highly nonlinear and dynamic. A demonstration project, real-time control of a beam balancing system based on fuzzy logic, is described. This prototyping system can be operated automatically by the execution of a fuzzy control algorithm. Unlike most of the conventional and optimal control algorithms, this fuzzy logic controller requires no explicit system parameters. It is characterized by its simplicity and robustness.<>
