An algebraic approach for dependable logic control systems design
نویسنده
چکیده
This article presents a formal method that enables to design a logic control system from specifications given in natural language. The aim of the proposed method is to prevent designer's faults coming from specifications misinterpretation. A significant part of the article is devoted to the presentation of the formal framework that underlies this formal design method: the algebra II. The operations and relations on this algebra allow to state formally specifications of a logic control system and to detect inconsistencies in a specifications set. This inconsistency problem is solved by introducing priority levels. From the consistent set of specifications obtained, control laws can be generated by using theorems and properties of the algebra II. An application of this formal design method to an industrial example permits to illustrate its main advantages.

AN ALGEBRAIC STRUCTURE FOR INTUITIONISTIC FUZZY LOGIC
In this paper we extend the notion of degrees of membership and non-membership of intuitionistic fuzzy sets to lattices and introduce a residuated lattice with appropriate operations to serve as semantics of intuitionistic fuzzy logic. It would be a step forward to find an algebraic counterpart for intuitionistic fuzzy logic. We give the main properties of the operations defined and prove som...

This paper addresses the design procedure of a fuzzy logic-based adaptive approach for DFIGs to enhance automatic generation control (AGC) capabilities and provide better dynamic responses in multi-area power systems. In doing so, a proportional-integral (PI) controller is employed in DFIG structure to control the governor speed of wind turbine. At the first stage, the adjustable parameters of ...

متن کاملADAPTIVE FUZZY TRACKING CONTROL FOR A CLASS OF PERTURBED NONLINEARLY PARAMETERIZED SYSTEMS USING MINIMAL LEARNING PARAMETERS ALGORITHM
In this paper, an adaptive fuzzy tracking control approach is proposed for a class of single-inputsingle-output (SISO) nonlinear systems in which the unknown continuous functions may be nonlinearlyparameterized. During the controller design procedure, the fuzzy logic systems (FLS) in Mamdani type are applied to approximate the unknown continuous functions, and then, based on the minimal learnin...
