On controllability and observability of fuzzy control systems
2018Summary: In order to more effectively cope with the real world problems of vagueness, imprecise and subjectivity, fuzzy event systems were proposed recently. In this paper, we investigate the controllability and the observability property of two systems that one of them has fuzzy variables and the other one has fuzzy coefficients and fuzzy variables ...

Fuzzy control as a fuzzy deduction system
Fuzzy Sets and Systems, 2001The author gives a new and interesting translation strategy for linguistic control rules of the form: \textit{if} \(x\) is \(A\) \textit{then} \(y\) is \(B\). He reads them as: \( A(x) \land B(y) \to\text{ good} (x,y) \) with a new predicate \textit{good} expressing globally the control quality.

Aggregated fuzzy control systems
Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002A multi-resolutional approach in generating a hierarchical and aggregated fuzzy system description is provided. The process includes aggregation of the fuzzy sets describing the control system as well as the aggregation of the rules that map a collection of fuzzy set to another set.

On Fuzzy Control of Chaotic Systems
Journal of Vibration and Control, 2004In this paper, we introduce the control of the strange attractor, chaos. Because of the importance of controlling undesirable behavior in systems. researchers are investigating the use of linear and nonlinear controllers, either to remove such oscillations (in power systems) or to match two chaotic systems (in secure communications).

Fuzzy logic in control systems: fuzzy logic controller. I
IEEE Transactions on Systems, Man, and Cybernetics, 1990For pt.I see ibid., vol.20, no.2, p.404-18, 1990. The basic aspects of the FLC (fuzzy logic controller) decision-making logic are examined. Several issues, including the definitions of a fuzzy implication, compositional operators, the interpretations of the sentence connectives 'and' and 'also', and fuzzy inference mechanisms, are investigated ...

Adaptive fuzzy control systems
Proceedings Electronic Technology Directions to the Year 2000, 2002Computer based process control systems have been used successfully for a number of years. However, these systems are often highly mathematical, are difficult to understand and implement, and are also inflexible. Fuzzy logic was developed in the early to mid 1960s by Lotfi Zadeh as an alternative to these complex traditional computer control schemes ...

Fuzzy systems in instrumentation: fuzzy control
Proceedings of 1995 IEEE Instrumentation and Measurement Technology Conference - IMTC '95, 2002This paper presents a short overview of fuzzy control and discusses fuzzy partition in comparison with classical A/D and dither quantification.

FUZZY LOGIC FOR CONTROL SYSTEMS
IFAC Proceedings Volumes, 1992Abstract Ever since fuzzy set theory was first proposed by Professor Zadeh, People in the control field have examined very carefully its applicability to the real world. Very few results of practical application were reported namely due to the difficulty of proving validity.

Accessibility of Fuzzy Control Systems
2011This paper presents a systematic methodology for delineating the accessibility of fuzzy logic control systems (FLCSs). Accessibility is an essential prior step for determining the controllability of plants in which the state trajectories are verified if they are accessible to a full dimension set.

Fuzzy control of complex systems
Soft Computing - A Fusion of Foundations, Methodologies and Applications, 1997One of the biggest challenges of any control paradigm is being able to handle large complex systems. A system may be called large-scale or complex, here, if its dimension (order) is so high and its model (if available) is nonlinear, interconnected with uncertain information flow such that classical techniques of control theory cannot easily handle the ...
