Enhanced performance of PID load frequency controller for power systems Dola Gobinda Padhan; Suresh Kumar Tummala
International Journal of Advances in Applied Sciences Vol 8, No 2: June 2019
Publisher : Institute of Advanced Engineering and Science

A novel control structure for designing a PID load frequency controller for power systems is presented. The controller with a single tuning parameter is designed based on a desired closed-loop complementary sensitivity function and Pade approximation. Comparative analysis demonstrates that proposed PID controllers improves the settling time and reduces overshoot effectively against small step load disturbances. Also, the performance and robustness of the controllers have been analyzed and compared. Simulation results show significantly improved performances when compared with recent results.

The quick development of innovation has made our lives less demanding. Innovation has additionally expanded activity risks and street mishaps occur very often which cause tremendous death toll and damage to property on account of poor response from the people in charge of managing such incidents. The mishap recognition undertaking will give an ideal solution for this problem. An accelerometer or a Tilt Sensor can be used as part of an auto caution application with the goal that unsafe driving can be identified. It can be utilized as a crash or rollover finder of the vehicle amid and after a crash. With signals from a sensor, a serious situation because of an accident can be avoided or attended to at the earliest. At the point of time when a vehicle meets with an accident or an auto moves over, the tilt sensor recognizes the flag and promptly sends it to the microcontroller. The microcontroller sends the alarm message through the IoT Module including the location of the accident through the GPS Module to the police or control group by publishing it over the cloud. So, the crisis enable group can promptly follow the area through the GPS Module, subsequent to receiving and accepting the data. The area can likewise be seen on the Google maps. Vital move can be made if this data reaches the control group in time. This venture is valuable in recognizing the accident with the use of sensors. As a future execution, we can add a remote webcam to the current system in order to capture pictures of the scene of the accident.

Publisher : Institute of Advanced Engineering and Science

Monitoring the delivered power quality (PQ) to a critical load, is a worry issue since it is matter as much as critical or quality sensitive equipment connected to the electrical network. Various PQ problems such as noise, voltage imbalance, waveform distortion, phase imbalance, phase sequence, over voltage or sag are the most popular quality problems that could be detected and fixed if needed. The present work presents a design and practical implementation of electronic embedded system to monitoring the sequence of a three phase electrical system and detects the occurrence of any change in the sequence and fixes it online, correct the phase sequence immediately during less than 70 milli-seconds. PIC Microchip microcontroller has been used as the core of the present system, where the correction of the phases has been achieved by using traditional electromechanical relays. The system has been tested successfully and it functions properly even with multiple sequence changes.

Publisher : Institute of Advanced Engineering and Science

This paper discussed on the development of automated data acquisitioncircuits using the parallel port of a computer through Visual C++. The aim ofthis study is to produce low cost laboratory apparatus that are both accurateand easy to use. Two revisions of an accelerometer device are described in thispaper. Each prototype determined sources of errors (initial moment of inertia,device delay, code optimization) that were used in improving the design for thenext revision. For the first revision errors of 13.63% and 16.38% between theexperimental and theoretical values were recorded while the second revisionshowed errors of 12.58 % and 7.20 % on two different angles. The next revisionof the prototype would include the use of embedded assembly code in the Visual C++code together with advanced thread synchronization techniques to improve theaccuracy of the measured data.

A CFD Study with Fuzzy Logic Pitch Angle Turbine Control Implementation for OWC Generation System Mansour Madaci; Djallel Kerdoun
International Journal of Advances in Applied Sciences Vol 6, No 2: June 2017
Publisher : Institute of Advanced Engineering and Science

The paper takes the improvement of the performance for an OWC converter from the mechanical side. A FEM model of the OWC conversion structure was proposed, studied and simulated using a CFD simulator. A novel wave generation method was applied through the RWMD method (Real Wave Model Simulator) instead of using an ordinary sin wave generator on the tank to make the waves the closest possible to the real sea waves. A mechanical prototype was built for this purpose to get an oscillated wave model. On the electrical side, a pitch angle control system based on fuzzy set was applied on the turbine to be auto-adapted for the fast variation of the airflow speed to establish and maximize the extracted power from the OWC device. The model have been studied, simulated, implemented and tested to validate the obtained results.

An Attempt to Relate Consolidation Properties: A Case Study in Baghdad Cohesive Soil Abbas Jawad Al-Taie; Bushra S. Al-Busoda
International Journal of Advances in Applied Sciences Vol 2, No 2: June 2013
Publisher : Institute of Advanced Engineering and Science

The main focus of this study is on the soil properties (preconsolidation pressure (Pc), and overconsolidation ratio (OCR)), that are critical in the determination of the settlement behavior of the structure. Prior knowledge of these properties, even approximate values, will be assets during the planning stages to determine the suitability of structure site. Conducting laboratory tests for the determination of (Pc) will be costly both in terms of time and money. In the present study a specific empirical correlation models are proposed to estimate the (Pc) and (OCR) of undisturbed cohesive soil of Baghdad city using large number of consolidation data. The (Pc) and (OCR) are dependent variables and are treated as functions of natural void ratio (eo), natural moisture content (wo), total unit weight (gt) , dry unit weights (gd), and overburden pressure (Po) which are termed as independent variables. The regression analysis revealed that (eo) and (Po) yielded sufficiently reliable correlation to estimate (Pc). Also, a good estimation was obtained for (OCR

An Open Source Contact-Free Palm Vein Recognition System Ranjith Kumar M; Deepika G G; Meenakshi Krishnan; Karthikeyan B
International Journal of Advances in Applied Sciences Vol 6, No 4: December 2017
Publisher : Institute of Advanced Engineering and Science

In this document, we propose a novel palm vein recognition system using open source hardware and software. We have developed an alternative preprocessing and feature extraction technique. The proposed system is built on Raspberry Pi using OpenCV 2.4.12. The palm vein image is cropped to Region of Interest(ROI) to reduce the computational time in real time systems and then preprocessed to enhance the vein pattern visibility and to extract more number of key points using SIFT algorithm. Then the descriptors are stored in a dictionary like codebook file during training. Later the descriptors are tested with unknown patterns. The clustering is based on K-means algorithm and classification is done using Support Vector Machines (SVM).

Publisher : Institute of Advanced Engineering and Science

The study was carried out in Avu Junction in Owerri West L.G.A. at graded distant from the tarred road with an average vehicular flow between 10,000 to 12,000 per day. Soil samples were taken at the distant of 50m, 100m, 150m and 200m respectively. And auger soil samples were taken at the depths of 0-30 cm and 30-45 cm accordingly. Soil factor, heavy metals and microbial populations were investigated at graded distances. From the result of soil factors, pH values indicated acidity with decreased distant from the tarred road ranging between 4.52 – 6.32, soil temperature on the topsoil was higher than subsoil ranging between 19- 25 0C and 18 – 22 0C and soil moisture increases with increased distant from the tarred road ranging between 10.00 – 13.3. Heavy metal concentrations in the soil increased with decreased distant in the order of Pb < Zn < Ni < Cu < Cd. Overall results revealed that Cd in the soil constitutes the highest percentage of 91.7%, Ni 90.9%, Cu 90.1%, Pb. 84.7% and Zn. 81.7%. Significantly, higher fungi and bacterial populations were recorded at increased distant from the tarred road. This then called for proactive measures to checkmate soil contamination due to pollutants from vehicular flows.

International Journal of Advances in Applied Sciences Vol 1, No 1: March 2012
Publisher : Institute of Advanced Engineering and Science

The paper examined the radiation effect on unsteady MHD free convection heat and mass transfer flow on a viscous, incompressible, electrically conducting fluid past a vertical permeable moving plate with radiation. The non-linear partial differential equations governing the flow have been solved numerically using finite element method. Graphical results for velocity, temperature and concentration profiles have been obtained, to show the effects of different parameters entering in the problem. Such flow problems are important in many processes, in which there is combined heat and mass transfer with radiation. It has been observed that the velocity increase with the increase in the radiation parameter and there is a increase in temperature with the increase in the value of radiation parameter.Keywords: Heat and Mass transfer, MHD, Radiation, FEM
