This research work presents the wind energy conversion system with maximum power tracking system using an expert system like fuzzy logic. The extraction of the maximum possible power available wind energy is an important area of research among the speed sensorless MPPT control of wind area. This paper presents a power point tracking (MPPT) Technique for high performance wind turbine with induct...

In this short paper we present a discrete-time eld oriented controller (FOC) for current-fed induction motors which insures global asymptotic speed regulation as well as rotor ux norm tracking. To the best of our knowledge, this is the rst time such a result is rigourously established for a controller implemented in discrete-time. To insure global stability a condition on the reference for the ...

13 Much of our interaction with the visual world requires us to isolate some currently important objects from other less 14 important objects. This task becomes more difficult when objects move, or when our field of view moves relative to the 15 world, requiring us to track these objects over space and time. Previous experiments have shown that observers can track a 16 maximum of about 4 moving...

This paper presents a scalable, discreet and mobile video-camera system that takes elevated video data of roadway locations for traffic safety analysis. The video is used to extract microscopic traffic parameters including road-user trajectories, lane changes and speeds. Collected video data is processed using an open-source automatic tracking tool. Trajectories can be then used to analyse road...

This study tested whether multiple-object tracking—the ability to visually index objects based on their spatial-temporal history—is scene-based or image-based. Initial experiments showed equivalent tracking accuracy for objects in 2D and 3D motion. Subsequent experiments manipulated the speed of object motion independently from the motion speed of the scene as a whole. Results showed that track...

This paper presents a new algorithm based on Model Reference Adaptive System (MRAS) and its stability analysis for sensorless control of Doubly-Fed Induction Generators (DFIGs). The reference and adjustable models of the suggested observer are based on the active power of the machine. A hysteresis block is used in the structure of the adaptation mechanism, and the stability analysis is performe...

ABSTRACT: The wind turbine generator is operated such that the rotor speed varies according to wind speed to adjust the duty cycle of power converter and maximizes wind energy conversion system efficiency. The rotating speed of permanent-magnet generator should be adjusted in the real time to capture maximum wind power. This paper proposes a quite simple maximum power point tracking control sch...

Human foot motion localization based on Inertial Measurement Unit (IMU) sensor especially in large environments has many potential applications such as search and rescue in fire or in emergency, navigation for visitor and security purposes, etc. However, current existing algorithms are so far from practical applications. Because they usually apply a fixed threshold for human gait phase detectio...

Due to its open characteristic, the Web is being posted with vast amount of new information changes continuously. Consequently, at any time, it is conceivable that there will be hot issues (emerging topics) being discussed in any information area on the Web. However, it is not practical for the user to browse the Web manually all the time for the changes. Thus, we need this Emerging Topic Track...
