    This paper reviews current methods of integrating genetic algorithms with fuzzy logic control. A fuzzy logic controlled genetic algorithm (FLC-GA) is proposed where operator selection and parameter adjustment is carried out dynamically and automatically. The fuzzy logic controller facilitates this automated control by employing an associated rule base and inference engine. This decides, using feed... View full abstract»

    The paper focuses on the speed control of stepping motors in a closed-loop configuration. An incremental optical encoder is used as the position transducer, allowing the achievement of a minor loop. The numerical control algorithm is implemented using an IBM PC together with a specialized interface for stepper motors. The solution was obtained in two steps: the first was a nonlinear control law an... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (464 KB)

    In this paper, the task of integrating conflicting experts' opinions is achieved through a training of local receptive gating network using backpropagation. The front layers of the gating network consist of local-receptive fields which form feature maps of the input that enable modulations to experts' output. The resulting network achieves accurate modelling of the solution mapping through the eff... View full abstract»

    This paper describes the experimental use of a new technique for the condition monitoring of rolling element bearings. The incremental motion encoder (IME) is a new type of rotary motion sensor that can measure the relative motion between a shaft and its supporting bearing. This motion is directly related to the condition of the bearing. The advantage of this method, over the measurement of transm... View full abstract»

    A new segmentation-free method, called N-markers, is proposed for machine recognition of the Arabic printed texts. The contribution aims at the optical character recognition of printed texts, like books and journals of good quality, usually typeset in so-called Naskhi font. The focus of attention is shifted from the recognition of multifont texts to that of single Naskhi font, taking, however, int... View full abstract»

    Fuzzy theory is very popular and useful on the control field. The main problem arises when we ask for how can be chosen the membership function and operators. There are some consensus, although theoretical basis of the problem is missing. Our objectives is to give an answer for the assessment of membership function, of logical operators and of unary operators View full abstract»

    It is a well-known fact that batch processes are gaining wider ground in chemical industries. Compared with continuous processes the control of batch processes is more difficult because of the physical and chemical properties of the contents, such as heat capacity, heat transfer coefficient and reaction rate, which vary from run to run and within runs. The control problem focuses on the temperatur... View full abstract»
