这篇英文论文主要介绍了基于TI公司TMS320C24x的直流无刷电机控制。A complete solution proposal is
presented below: control structures, power hardware topology, shaft
position sensors, control hardware and remarks on energy conversion
efficiency can be found in this document.
We describe and demonstrate an algorithm that takes as input an
unorganized set of points fx1􀀀 􀀀 xng 􀀀 IR3 on or near an unknown
manifold M, and produces as output a simplicial surface that
approximates M. Neither the topology, the presence of boundaries,
nor the geometry ...
The advantages of automation can be exploited in order to solve or to
minimize the needs of manual approach. In order to support the development of
survey accurate cadastral system, an automatic programming approach will be
adopted. Database selection system will conduct several outliers integrity
c ...
With the Wireless module, OPNET can model both
terrestrial and satellite radio systems. In this tutorial,
you will use Modeler and Wireless modeling to create a
radio network you will also observe variations in the
quality of received signal that results from radio noise
at the receiving node in a ...
In the next generation of wireless communication systems, there will be a need for the rapid
deployment of independent mobile users. Significant examples include establishing survivable, efficient,
dynamic communication for emergency operations, disaster relief efforts, and military networks. Such
n ...

DistMesh is a simple MATLAB code for generation of unstructured triangular and tetrahedral meshes. It was developed by Per-Olof Persson (now at UC Berkeley) and Gilbert Strang in the Department of Mathematics at MIT. A detailed ...
The ability to analyze system or circuit behavior is one of the key requirements for
successful design. To put an idea to work, a designer needs both the knowledge
and tools for analyzing the behavior of that new system architecture or that experi-
mental circuit topology. Design decisions are groun ...
This document provides general hardware and layoutconsiderations and guidelines for hardware engineersimplementing a DDR3 memory subsystem.The rules and recommendations in this document serve as aninitial baseline for board designers to begin their specificimplementations, such as fly-by memory topo ...
