Vague controller: A generalization of fuzzy logic controller
International Journal of Systems Science, 1999In this research, a vague controller (VC) is synthesized by using the notion of vague sets, which are a generalization of fuzzy sets and characterized by a truth-membership function and a falsity-membership function. The vague sets follow the basic set operations and logic operations defined for fuzzy sets, and are superior to fuzzy sets in that they ...

The fuzzy set notion enables us to define the progressive membership of an element to a class, that is to say it belongs to this class more or less strongly. The membership of an object in a class defines a degree of membership given between 0 and 1.

Design of a fuzzy logic controller as a suction controller
Fuzzy Sets and Systems, 1997Abstract A fuzzy logic controller (FLC) designed as a suction controller is proposed. Firstly, we prove that there exists a switching line in the FLC, and the slope of the switching line is determined by scaling factors. Secondly, a Lyapunov function is selected and sufficient conditions for the fuzzy control system (FCS) to be globally ...

Hardware implementation of fuzzy logic controller
2005 12th IEEE International Conference on Electronics, Circuits and Systems, 2005Fuzzy logic controllers are generally implemented on microprocessors which offer a smooth design surface. The purpose of this article is the implementation of a fuzzy logic controller on a field programmable gate array. The use of field programmable gate array gives the designers the possibility to implement a wide variety of applications, test them ...

In this chapter we review previous results in the effort to incorporate approximate reasoning into the control of physical processes. In particular, we wish to review the research in fuzzy logic control and show how the research presented here is a logical extension of that work.

Fuzzy Set Theory, introduced by Zadeh in 1965 [77], has been the subject of much controversy and debate. In recent years, it has found many applications in a variety of fields. Among the most successful applications of this theory has been the area of Fuzzy Logic Control (FLC) initiated by the work of Mamdani and Assilian [36]. FLC has had considerable
