BRUSHLESS DC MOTOR SPEED CONTROL USING MICROCONTROLLER 1G.SanthoshKumar, S.Arockia Edwin Xavier Thiagarajar College of Engineering ,Electrical and Electronic Engineering Madurai,Tamil Nadu Email: 1Santhoshg92@gmail.com,2saexee@tce.edu ABSTRACT The hardware project is designed to control the speed of a BLDC motor using closed loop control technique. BLDC motor has various application used in industries like in drilling, lathes, spinning, electric bikes etc. The speed control of the DC motors is very essential. This proposed system provides a very precise and effective speed control system. The user can enter the desired speed and the motor will run at that exact speed. KEYWORDS: Hall position sensors, Brushless DC motor, Microcontroller. INTRODUCTION Permanent-magnet excited brushless DC motors are becoming increasingly attractive in a large number of applications due to performance advantages such as reduced size and cost, reduced torque rip
Administrative Law of the United States the twenty-first century Richard B. Stewart Administrative law in a free and democratic society, its own administrative rules and regulations will be subject to administrative regulations. Administrative law established executive in the entire political system in the framework of status; set to take a decision that the executive must follow the procedural requirements; provides for an independent judiciary may be to review the possibility of administrative acts and scope. It to the administration and the administrative regulations of the various key areas in the provision of the universal principles and procedural requirements. Traditionally, the essence of administrative law focuses on how the executive authorities in accordance with the fair and unbiased process, The statutory mandate and to respect the private rights of way to such acts to ensure the rule of law protection of freedom. Here, the functions of administrative law is a n

英语原文共 7 页, 一种基于CFD的室内环境和空间通风控制的试验方法 摘要 系统动力学仿真已经被应用于测试和评估空调系统的本地控制和监督控制超过二十年,在此期间模拟空间通风的模型通常使用理想混合模型。然而,复杂混合空气模型无法考虑到不均匀空气温度分层的影响。本文提出了一种基于CFD的虚拟测试方法,通过将通风的房间与通风控制系统相结合来控制和优化室内环境。通风的房间及其动力学通风控制系统通过计算流体动力学(Computational Fluid Dynamics,CFD)模型和温度传感器模型、比例-积分-微分(Proportion Integration Differentiation,PID)控制器和制动器模型、变风量(Variable Air Volume,VAV)风门模型来描述。通风及其控制系统通过用户自定义函数程序编程并与CFD模型接口。开发了空间温度补偿模型作为虚拟传感器来提
英语原文共 9 页, 摘要— 在这篇文章中,我们提出一种从视频监控中检测人类摔倒的方法。第一步,使用改进的GMM执行背景消除法以找到前景对象。在第二步骤中,基于人类模板的轮廓匹配对人类或非人类对象进行分类。通过模型匹配后产生的分数突然变化,帮助检测跌倒事件。在第三步中计算高宽比,以确定人体形状是否改变。第四步,计算覆盖人的矩形的顶部和中心之间的距离,如果该距离小于某个阈值,则确定人跌倒。最后,如果人的不活动姿势持续到连续100帧,则将生成警报以提醒家中的人及时提供治疗。已经对含有不同的正常和异常跌倒事件的21个视频序列进行了实验。实验结果表明,该系统可以实时有效地识别人的跌倒。 关键字:人类跌倒,前景物体,高宽比,轮廓。 I. 引言和相关研究 通过视频监视进行人
外文标题:A New Method of Virtual Reality Based on Unity3D 文献出处:international Conference on Geoinfbrmatics, 2010 :l-5 Abstract—In the area of geographic information system, there are always two methods to get 3D virtual reality, one is to use a 2D professional platform such as ArcGIS software to get the virtual reality by secondary development, the other is to use a 3D or 2.5D software as a platform for development, such as the Skyline software. In this paper, we will use a different platform, Unity3D. which is usually treated as game development software, as a virtual reality development platform. Firstly, the hierarchical approach of geographic information system is adopted in the study area, and the arca is divided into four layers: Terrain Layer, Building Layer, Transport Layer, Vegetation Layer, additionally, the raw data of Terrain Layer is obtained by GPS measurements. Secondly. all the geographical entities which related to different laye
