This paper examines the dynamics and control of a variable blade pitch wind turbine during extreme gust subject to actuators saturation. The mathematical model is derived using Lagrange dynamics. controller formulated Takagi–Sugeno fuzzy utilizes parallel distributor compensator obtain feedback gain. controller’s objective generator electromagnetic torque angle attenuate external disturbances. ...

Adolescents are often sensitive to peer rejection, a factor that might contribute to the risk of affective disorder in this age group. Previous studies suggest a significant overlap among socioaffective brain regions involved in the response to social rejection, regions continuing to develop functionally during adolescence and regions influenced by monoamine oxidase A (MAOA) polymorphism. The c...

This paper presents quality Clay-Brick selection process based on intuitionistic fuzzy multi criteria group decision making through grey relational analysis. Brick plays an important role in construction field. Intuitionistic fuzzy weighted averaging operator is used to aggregate individual opinions of decision makers into a group opinion. Six criteria are considered for selection process and t...

In this paper, a new formula-based fuzzy proportional-integral (FPI) controller is proposed. This controller is based on the conventional proportional-integral (PI) controller. The proposed FPI controller has a linear structure similar to that of the conventional controller, and the operation of the proposed controller is based on analytical formulas. The structure is designed by using three me...

In this paper we addressed the problem of improving the control of AC motors used for the specific application of 3 degrees of freedom moving base flight simulator. Indeed the presence of backlash in DC motors gearboxes induces shocks and naturally limits the flight feeling. A comparison is hence set up between two techniques aiming to deal with this problem: Adaptive Fuzzy Controller and Neura...

Compared to physiologically based biometric systems such as fingerprint, face, palm-vein and retina, behavioral based biometric systems such as signature, voice, gait, etc. are less popular and many of the research in these areas are still in their infancy. One of the reasons is due to the inconsistencies in human behavior which requires more robust algorithms in their developments. In this pap...

This paper proposes an effective framework for interactive region-based image retrieval. By utilizing fuzzy coarse segmentation and the graph structure for representing each image, the retrieval process was performed by measuring the image similarity according to the graph similarity. To assess the similarity between two graphs, fuzzy inter relations among regions feature vectors and spatial di...
