Electric field control of magnetism is an extremely exciting area research, from both a fundamental science and applications perspective has the potential to revolutionize world computing. To realize this will require numerous further innovations, in arena as well translating these scientific discoveries into real applications. Thus, article attempt bridge gap between condensed matter physics a...

Because an electric scooter driven by permanent magnet synchronous motor (PMSM) servo-driven system has the unknown nonlinearity and the time-varying characteristics, its accurate dynamic model is difficult to establish for the design of the linear controller in whole system. In order to conquer this difficulty and raise robustness, a novel adaptive modified recurrent Legendre neural network (N...

It has been known for more than 2000 years that some fish can induce painful, numbing sensations when handled. In the late 1600s, it was discovered that this sensation resulted from the production of strong electrical currents produced by the fish (Kellaway 1946). In On the Origin of Species by Means of Natural Selection (1859), Darwin paid special attention to difficulties with his theory, dev...

some of the important mechanical loads in the civil and military industries are variable speed and power and their efficiency. mechanical coupling of two different electric motors is suitable for these types of application. using this technique reduces energy consumption of submarine’s motion system and submarine range would be increased. but the use of this technique requires a complex control...

The variable reluctance electrical machines had an essential role in the changes in electric machine technology during the last 30 years, when digital and power electronics and computerized design methods suddenly started to expand. As new boundaries are set up in both power electronic devices and digital control, the researchers reacted with new inventions and adaptations of electrical machine...

Most of the present day electric scooters are equipped with a voltage-driven DC motor powered by four 12-volt leadacid batteries and a hand-lever accelerator operated by the rider to control their speed. Because of the nonlinear battery discharge characteristics and different driving behaviors of riders, it is not easy to tell how much electric power remaining in the battery and how far the ele...

This paper present a general overview of the motion control system blocks, specially that related with motor considerations and torque control. Moreover, some trends in motor control systems are also presented.

Energy delivery at well construction in regions with hard climate is distinguished by variable demand in electric and heat power. Energy consumption of drilling equipment, production and living facilities varies greatly during the year, depending on power load charts and climate conditions. Power supply of remote well construction sites is mostly accomplished by operating autonomous power sourc...

This paper presents a hierarchical control strategy for heat and electric power control of a building integrating hybrid renewable power sources including photovoltaic, fuel cell and battery energy storage with Plug-in Electric Vehicles (PEV) in smart distribution systems. Because of the controllability of fuel cell power, this power sources plays the main role for providing heat and electric p...
