Using fuzzy logic in control applications: beyond fuzzy PID control
Stephen L. Chiu · IEEE Control Systems · 1998
Fuzzy logic is used mostly to handle high-level control functions that traditional control methods do not address. This article discusses different ways that fuzzy logic can be used in high-level control functions. Specifically, we examine the use of fuzzy logic for supervisory control, for selecting discrete control actions, for identifying the operating environment, and for evaluating controller performance. The purpose of this article is to stimulate the use of fuzzy logic to provide new control functions that are outside the domain of traditional control, where fuzzy control is likely to provide the greatest payoff.
