This paper presents the comparative analysis between the speed control of electronically commuted Brushless DC motor (BLDC) using conventional controllers like Proportional Integrative (PI) controllers, Simple Fuzzy Logic Controller (FLC) and Hybrid Fuzzy - PI controller with the help of MATLAB / SIMULINK. The conventional PI controllers are the most useful controller in industries until now. But it gives the poor performance under various operating conditions and for non-linear mode as compared to FL controller. The simples FLC is easy to develop but it sometimes cannot use in motor application and also needs automatic tuning. It takes more time and memory space while running on real time application. So to overcome this problem, Hybrid Fuzzy - PI controller is proposed. In the proposed system Fuzzy controller is tuned with conventional PI controller by using only 21 Mamdani linguistic rules. The proposed system improve the performance of motor and other operating condition such as rise time, settling time, percentage of overshoot and stability phenomenon etc. The response of the system can be observed from the above controllers with the help of MATLAB / SIMULINK.
本文利用MATLAB / SIMULINK对传统控制器如比例集成(PI)控制器、简单模糊逻辑控制器(FLC)和模糊- PI混合控制器对电子换向无刷直流电动机(BLDC)的速度控制进行了比较分析。传统的PI控制器是目前工业上最有用的控制器。但与FL控制器相比,它在各种工况和非线性模式下的性能较差。简单的FLC易于开发,但有时不能用于电机应用,还需要自动调谐。在运行实时应用程序时需要更多的时间和内存空间。为了克服这一问题,提出了模糊- PI混合控制器。在该系统中,模糊控制器仅使用21个Mamdani语言规则与传统PI控制器进行调谐。该系统改善了电机的性能,改善了上升时间、沉降时间、超调率和稳定现象等运行条件。借助MATLAB / SIMULINK,可以从上述控制器上观察系统的响应。

A critical issue in wireless sensor networks is to extend the network lifetime by preserving the energy of sensor nodes. A sensor node consumes most of its energy during the data transfer phase. The energy consumed for transmission of data is a thousand times higher than sensing and processing the same amount of data. Data aggregation is a promising technique that is used for minimizing the amount of data transfer in a sensor network, which helps in reducing the energy consumption. The existing data aggregation protocols have focused on objectives like minimizing the energy consumption, maximizing the lifetime of the network and reducing the end to end delay. However, these techniques do not consider duty cycling approach to lower energy consumption. In this paper, we propose an Energy Aware Chain Oriented Sensor Network protocol (EA-COSEN). The proposed protocol is an extension of existing COSEN [1] protocol and it uses duty cycling to save the energy of the sensor nodes. Our simulation results confirm that there is 2% to 3% improvement in throughput, residual energy and delay.
无线传感器网络的一个关键问题是如何通过保持传感器节点的能量来延长网络寿命。传感器节点在数据传输阶段消耗的能量最多。传输数据所消耗的能量比感知和处理同样数量的数据要高出一千倍。数据聚合是一种很有前途的技术,用于最大限度地减少传感器网络中的数据传输量,这有助于降低能耗。现有的数据聚合协议主要关注最小化能耗、最大化网络生命周期和减少端到端延迟等目标。然而,这些技术并没有考虑到占空比的方法来降低能耗。本文提出了一种面向能量感知链的传感器网络协议(EA-COSEN)。提出的协议是现有COSEN[1]协议的扩展,它使用占空比来节省传感器节点的能量。我们的仿真结果证实,在吞吐量、剩余能量和延迟方面有2%到3%的改善。

The concept of distributed energy is becoming integral to the smart grid paradigm. Cleaner and renewable sources like solar energy, in the form of photo voltaic systems, are being integrated at the lowest level of the power grid - the distribution network. However rising penetration of such distributed sources may cause operational issues like unintentional islanding which remains a concern among utilities. This work tries to create and analyze situations which are expected to develop frequently in the high penetration scenario and explore their impacts on possibility of unintentional islanding. Dynamic simulations are run for a modified IEEE feeder and potential precursors to accidental islanding are identified. Load-photo voltaic interactions and gridside disturbances are the situations that cause unique anomalous behaviour in grid-side current. Experimental observations on laboratory hardware also showcase similar behaviour albeit on a simpler network containing a different load model. Simulations are run again to reproduce the experimental observations. Such approach intends to create a predictive framework for islanding detection in real time.
分布式能源的概念正在成为智能电网范例的一部分。更清洁的可再生能源,如太阳能,以光伏系统的形式,正被整合到电网的最低层——配电网。然而,这种分布式能源的日益普及可能会导致运营问题,如意外孤岛,这仍然是公用事业公司关注的问题。这项工作试图创造和分析在高渗透场景中可能经常出现的情况,并探讨它们对意外孤岛可能性的影响。对一种改进的IEEE馈线进行了动态仿真,找出了意外孤岛的潜在前兆。负载-光伏相互作用和电网侧扰动是导致电网侧电流独特异常行为的情况。在实验室硬件上的实验观察也显示出类似的行为,尽管是在一个包含不同负载模型的更简单的网络上。再次进行模拟以再现实验观察结果。这种方法旨在为实时孤岛检测创建一个预测框架。

Electromagnetic radiations are phenomena that take the form of self propagating waves in a vacuum or in matter. Microwaves are a part of the electro-magnetic (EM) radiation spectrum, with a frequency range of 300Mhz to 300Ghz.Microwave heating is applied in ceramics, Metallic powder, Food products, Wood, Polymers, Rubber, Textile & Paper. Various sources of microwaves include the Magnetron, Klystron, Travelling-wave tube (TWT) and gyrotron. These devices work in the density modulated mode rather than the current modulated mode. This means that they work on the basis of clumps of electrons flying through them, rather than using a continuous stream. The scope of this project work requires us to focus on such a device namely Magnetron. Microwave wave heating has advantages over the conventional heating due to which it is finding applications in industries for heating. The heart of every microwave oven is a high voltage system whose purpose is to generate “Microwaves”. This high voltage system is called as Magnetron power supply. The power supply designed for a 1.2 kW magnetron, with primary anode current control, performed according to the specifications proposed at the beginning of the development. The various parameters were monitored such as anode current and the output power. Also the required interlocks / protections were checked.
电磁辐射是在真空或物质中以自传播波的形式出现的现象。微波是电磁(EM)辐射频谱的一部分,频率范围为300Mhz至300Ghz。微波加热应用于陶瓷、金属粉末、食品、木材、聚合物、橡胶、纺织和造纸等行业。微波的各种来源包括磁控管、速调管、行波管和回旋管。这些器件工作在密度调制模式,而不是电流调制模式。这意味着它们的工作原理是基于成群的电子穿过它们,而不是使用连续的电子流。这个项目的工作范围要求我们关注这样一个设备,即磁控管。微波加热比传统加热有优势,因此它在工业加热中得到了应用。每台微波炉的核心都是一个高压系统,其目的是产生“微波”。这种高压系统称为磁控管电源。该电源设计用于1.2 kW磁控管,具有初级阳极电流控制,根据开发开始时提出的规格进行。对阳极电流和输出功率等参数进行了监测。还检查了所需的联锁/保护。

Probability distributions are used to represent uncertainty. One area of application of probability distribution is optimization under uncertainty more specifically known as Stochastic Integer Programming. Distributions with large number of scenarios increase computational complexity. Fast Forward Selection scenario (FFS) reduction algorithm provides a way to approximate the probability distribution. The paper applies FFS to a gaussian distribution and estimates the original distribution with lower number of scenarios while maintaining the overall variation of probability curve similar to the original curve. New probability density of the approximated distribution is close to the original distribution.

This work suggests the method to improve the performance of interacting coupled tank system by the combinational control of feedback and feed forward simultaneously. This control system is considered to maintain the level of the second tank at some predefined value by using feed forward and feedback combinational scheme. Though conventional proportional integral- derivative (PID) controller is most capable controller used in process industries to regulate the process variables, it has some limitations which can be overcome by using this strategy. Here, the effect of disturbance on the performance of the system is considered. According to these disturbances, we implemented a feed forward controller to compensate the disturbances with its effect on the performance of the system. Thus, the comparison between feedback and feedback feed forward implementation for the system is done using MATLAB simulink and experimentation is carried out.

An automatic detection of Proliferative Diabetic Retinopathy 增生性糖尿病视网膜病变的自动检测
Pub Date : 2015-10-01 DOI: 10.1109/ICESA.2015.7503318

The Proliferative Diabetic Retinopathy (PDR) is a stage of retinopathy where blood vessels proliferate i.e. grows. The indication of PDR is neovascularization, the growth of abnormal new vessels. Here, first vessel segmentation is done by converting image into binary image. So that vessel and non-vessel part is seperated. By using morphological operation and structuring element as line, straight vessels are detected and removed. So remaining part is new vessels. These morphological operations are taken for multiple orientations like 45°, 90°, 135°, 180°. Straight vessels were removed to distinguish new vessels from normal vasculature. Morphological thinning is used to thin only new vessels. Feature extraction is done by windowing image into 50 by 50 in order to calculate number of vessel pixels in every window. If numbers of vessel pixels are greater than threshold value then PDR is detected.
增殖性糖尿病视网膜病变(PDR)是视网膜病变的一个阶段,血管增生,即生长。PDR的指征是新生血管的形成,即异常新生血管的生长。在这里,首先通过将图像转换为二值图像来进行血管分割。所以血管和非血管部分是分开的。通过形态学运算,以结构元素为线,对直血管进行检测和去除。剩下的部分是新的血管。这些形态学操作可以在45°,90°,135°,180°等多个方向上进行。切除直血管以区分新生血管和正常血管。形态学变薄仅用于变薄新生血管。特征提取的方法是将图像分成50 × 50的窗口,计算每个窗口的血管像素数。如果容器像素数大于阈值,则检测到PDR。

In the process of steel making, rolling mills play a vital role in transforming the steel to finished products. Rolling mills at a steel producing plant consists of Light and Medium Merchant Mill and Wire Rod Mill. The blooms from Steel Melt Shop are charged into reheating furnaces of Light and Medium Merchant Mill for heating them up to 1200°C and subsequent rolling is performed with required specifications. Reheating furnace at LMMM of 200 ton/hr. capacity is running with the by-product energies as fuel and yielding limited output up to 150 ton/hr. of steel for rolling. This reduction in the furnace output was to be examined by performing Heat Balance over the furnace. The furnace parameters were collected for about 10 days to prepare an average heat balance of the reheating furnace. Improvements were made to augment the overall thermal efficiency of the furnace and the data is furnished.

Improvements were made to augment the overall thermal efficiency of the furnace and the data is furnished.","PeriodicalId":259816,"journal":{"name":"2015 International Conference on Energy Systems and Applications","volume":"6 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113959939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In power system operation, congestion management has become more complicated with the increase of system complexity in deregulated environment. That is why, in present scenario of power system congestion management is a complex task of an independent system operator (ISO). In this paper, generator rescheduling is used as a congestion management technique. A recently developed meta heuristic algorithm known as Firefly Algorithm (FA) has been introduced in proposed work. The present work is two folded. Firstly, Generator sensitivity factor (GSF) is calculated to identify the generators participating in congestion management by rescheduling their output. Secondly, FA is introduced to find optimal rescheduling cost of participating generators. Present work is tested on IEEE 39 bus New England Test System.
在电力系统运行中,随着系统复杂度的增加,在放松管制的环境下,拥塞管理变得更加复杂。这就是为什么在目前的情况下,电力系统拥塞管理是一个复杂的任务,一个独立的系统运营商(ISO)。本文将发电机重调度作为一种拥塞管理技术。本文介绍了一种最近发展起来的元启发式算法——萤火虫算法(FA)。现在的作品是折叠的。首先,计算发电机灵敏度因子(GSF),通过重新调度输出来识别参与拥塞管理的发电机。其次,引入遗传算法求解参与发电机组的最优重调度成本。本文在ieee39总线新英格兰测试系统上进行了测试。
