In order to improve the resolution and accuracy of the Ground-Penetrating Radar (GPR) forward modeling, this paper will focus on applying the mesh less algorithm-Element Free Method(EFM)which is widely used in the electromagnetism field into the radar numerical simulation. The EFM is dispensed with the concepts of elements, just needs a mass of node information and adopts the Moving Least Squares...
This paper discusses the necessity of synchronous generator leading phase operation adjusting voltage, combined with Jiangsu power grid generator leading phase operation experiment situation. It proposed that generator leading phase operation is a convenient and economic voltage regulation means of power grid. Characteristics of 600 MW synchronous generator leading phase operation are studied through...
After analyzing the basic principle of sensorless control using extended Kalman filter (EKF) in permanent magnet synchronous motor (PMSM) drive, this paper proposes an intelligent sensorless control. Here, fuzzy control is used in EKF and neuron control is used in speed loop, since neuron based speed controller does not rely on the accurate mathematical model of system, and it has not only fast dynamic...
