Making electrical driving systems cheaper, lighter, and more reliable is the consistent pursuit of current research development. Mono-inverter multipermanent magnet synchronous motor tend to share static converters in electromechanical by connecting machines parallel. This type system has an obvious advantage overall weight cost. In this article, we have proposed a new maximum torque per ampere...

The estimation of the state charge (SOC) a battery’s power is one key technologies in battery management system (BMS). As common SOC method, traditional ampere-hour integral method regards actual capacity battery, which constantly changed by usage conditions and environment, as constant for calculation, may cause errors results estimation. Considering above problems, this paper proposes an impr...

The algorithmic structure of a vector controller capable of high quality speed control of a synchronous reluctance motor with and without the use of a rotor position sensor is presented in this paper. The controller is based on a conventional saturated machine d-q model. Its main merit is that it can be operated in a sensorless control mode by executing a new, very accurate parameter dependent ...

A reference standard for a unit of measurement is an artifact that embodies the quantity of interest in a way that ties its value to the reference base. The selection of an appropriate reference standard is a crucial point in the performance evaluation of wire rope electromagnetic testing (EMT) instrument. In this paper, a 3-D finite element model (FEM) has been developed to study three referen...

In this work a new resistorless sub-bandgap voltage reference topology is presented. It is a self-biased and small area circuit that works in the nano-ampere consumption range, and under 1 V of power supply. The behavior of the circuit is analitically described, a design methodology is proposed and simulation results are presented for a standard 0.18 μm CMOS process. A reference voltage of 463 ...

This paper is concerned with the existence of globally smooth solutions for the second boundary value problem for Monge-Ampere equations and the application to regularity of potentials in optimal transportation. The cost functions satisfy a weak form of our condition A3, under which we proved interior regularity in a recent paper with Xi-nan Ma. Consequently they include the quadratic cost func...

On any compact Kähler manifold, Mabuchi [16], Semmes [17], and Donaldson [5] introduced a Weil-Peterson type metric in the space of Kähler metrics and proved that it is a formally non-positively curved symmetric space of “noncompact” type. According to [17], the geodesic equation can be transformed into a homogenous complex Monge-Ampere equation. In [5], Donaldson proposed an ambitious program ...

Automatic piloting of unmanned aerial vehicles(UAVs) is vital for the safety UAVs and optical image quality acquired by them. In previous effort, automatic pilot method based on or GPS (global position system). Inspired bird migration using terrestrial magnetic field, a novel autopilot field sensing above 10 kV OHLs (overhead lines) proposed in this paper to achieve routine inspection. The resu...
