This work focuses on micro-grid, containing various alternative energy resources (wind and photovoltaic) and super-capacitor energy storage system which performs in stand-alone as well as in grid-connected modes. Various non-isolated converters are used to control the proposed micro-grid. A classical-based supervisory control scheme is designed to perform energy management in order to satisfy the...
To achieve a succesful electromagnetic interference simulation and analysis among lots of electromagnetic equipment deployed in wide range, passing the time-varying spectrum simulation parameters to each simulation terminal quickly and in time is a critical factor. This paper proposes an electromagnetic propagation simulation platform, in which all the simulation terminals acquire part of the simulation...
There are many abstract concepts and mathematic theory in electron information specialty which are difficult to understand. Experimentation is the necessary part of teaching process. Simulation analysis of SystemView can renovate experiment contents expediently. This paper discusses the application of SystemView in experiment teaching of electron information specialty. The practice shows that the...
Because of small volume of the mini autonomous underwater vehicle, the ability to resist the wave and the current disturbance is not ideal enough. The present motion models ignore the effect of the external disturbance, and even ignore the fin effective angle of attack. In this paper, we establish a dynamic motion model of the mini autonomous underwater vehicle which can describe the motion accurately...
This paper proposes a novel sliding mode reference adaptive system(SM MRAS) observer for speed identification in a sensorless direct torque control induction motor system. The SM MRAS method uses the voltage model (VM) as reference and the current model (CM) as adjustable model to estimate the motor speed by combining MRAS with sliding mode variable-structure control to formulate a slide mode surface...
A handover arithmetic of air-to-ground data communication over-section networking was proposed to settle the problem of low handover success rate and data throughput. The simulation results show that after introducing the arithmetic over-section handover success rate will improve greatly in the case of ideal wireless space, and some advantage will display.
