Performance Analysis of Brushless DC Motor under Different Loading Conditions

This paper deal with the speed response characteristics analysis of brushless dc motor under different load variations. BLDC drive are widely used motors now a days due to its good speed control characteristics and high efficiency which improves the performance of motor. PI controller is used in motor operation to maintain the constant speed. The analysis is carried out in three different type of load condition which are given as under load, rated load and overload conditions. The performance of BLDC motor is observed through speed, current, back emf and torque response. To evaluate the result appropriate value of Kp and Ki of controller has been taken in order to get the better result for characteristics parameter of the speed response of BLDC motor. The result are then calculated mathematically and analysed according to the load variations. The required model has been developed using Simulink Matlab and speed torque characteristics graph is also analysed using PI controller.

An Automated ECG Signal Diagnosing Methodology using Random Forest Classification with Quality Aware Techniques

In this project, we put forward a new automated quality aware ECG beat classification method for effectual diagnosis of ECG arrhythmias under unsubstantiated health concern environments. The suggested method contains three foremost junctures i ECG signal quality assessment ECG SQA based whether it is “acceptable” or “unacceptable” based on our preceding adapted complete ensemble empirical mode decomposition CEEMD and temporal features, ii reconstruction of ECG signal and R peak detection iii the ECG beat classification as well as the ECG beat extraction, beat alignment and Random forest RF based beat classification. The accuracy and robustness of the anticipated method is evaluated by means of different normal and abnormal ECG signals taken from the standard MIT BIH arrhythmia database. The suggested ECG beat extraction approach can recover the categorization accuracy by protecting the QRS complex portion and background noises is suppressed under an acceptable level of noise . The quality aware ECG beat classification techniques attains higher kappa values for the classification accuracies which can be reliable as evaluated to the heartbeat classification methods without the ECG quality assessment process.

Importance of Solar Energy in Day to Day Life

The natural world has used the sun’s energy since the beginning of time, and while there has been lots of discussion about this, the truth is that the sun is both a problem and a solution. Solar energy is an unchanging constant – a staple in Earth’s very existence. The sun may not have changed, but our understanding of it has. We are now harnessing its energy to replace traditional methods that have taken a toll on the planet. Instead of burning fossil fuels like coal and natural gas, consumers can take advantage of the infinite energy of the sun to power homes, cars, and appliances. Explore these five everyday uses of solar energy to see how this resource can transform your future, not just the future.

Operating CNC and Laser Machine Everywhere using IoT

Computer numerical control CNC is programmed code that represents instructions for precise movements to be carried out by machines. Indirectly, this code defines how to automatically create, produce, or transform a virtual object into a real one. Laser GRBL is one of the best Windows GCodestreamer for DIY Laser Engraver. Laser GRBL can load and stream GCode path to Arduino, as well as engrave images, pictures and logo with the internal conversion tool. grbl is a fantastically simple and economical g code interpreter and CNC stepper motor controller for the Arduino, there doesn’t seem to be much information on how an average or new Arduino user should interface with it or how it works internally.

Study of Boundary Value Analysis in Structural Engineering and Fluid Mechanics using Homotopy Perturbation

This paper presents a focused study on properties of porous concrete to widen its application to structural engineering. Mechanical properties like compressive strength, indirect tensile strength, flexural strength and physical properties like density, permeability and porosity are studied. To determine those parameters, twenty seven cubes, cylinders and prisms were tested. Also, three polymer impregnated porous concrete slabs were tested under pure bending moment to study the efficiency of selected resin to integrate particle of concrete to achieve a new generation in using porous concrete in structural engineering. Three different cement content specimens of porous concrete were considered, studied cement contents are 200 kg m3, 300 kg m3 and 400 kg m3. The results show that, increasing the cement content can increase the compressive strength, indirect tensile strength and flexural strength. Density of porous concrete is less than conventional concrete by 21 but permeability factor recorded higher value compared to conventional concrete by sixteen times. Increasing the cement content has no significant effect on either ultimate load or maximum deflection of polymer impregnated porous concrete slabs but the results recorded an achievement to use this concrete in structural engineering applications and give an easy way to cast special concrete like polymer concrete without special tools.

Power Quality Improvement using Shunt Active Power Filter

Nowadays, usage of non linear loads in power system is increasing. For example, UPS, inverters, converters, etc. These loads make the supply current non sinusoidal and distorted form, which is called harmonics. At this time Active power filters have been developed to improve power quality. In this Paper, a Shunt Active Power Filter SAPF control scheme has proposed to eliminate the current harmonics and improve the power quality. The shunt active power filter controlled by using the different controllers such as PI, PID, Fuzzy logic, Pq Theory and hysteresis controller . In our proposed system, PI controller is used to reduce the harmonics current using the shunt active power filter. And both current THD results are compared, with and without use of filter and then shown how filters can reduce THD and is most suitable to control the shunt active power filter in term of total harmonic reduction THD . MATLAB SIMULINK power system toolbox is used to simulate the proposed system.
