Stepper motors are widely used in industrial and consumer applications due to their low cost, great dependability, and capability for open-loop control. Open-loop has a straightforward design, but it has a low step objective, a big torque wave, and low energy productivity. A new sensorless speed control structure based on hysteresis current regulator is proposed in order to work on the exhibition without increasing equipment costs. It does not convert currents between a-b and d-q coordinates using Park and inverse Park transformations, in contrast to the traditional sensorless speed control.The dynamic performance of the hysteresis current controller is excellent. It has been extensively studied and used in inverter fed drives and voltage source inverters. This approach provides quick dynamic performance and incorporates the virtual rectifier stage's line modulation methodology into the overall modulation. The outcomes of the simulation and experiment show that the suggested plan is efficient and workable. Through experimentation and evaluation of the suggested controller's speed and position tracking capabilities, MATLAB/Simulink simulation (R2020a) is used to confirm its efficacy.

This work suggests a practical control scheme for a battery charger for an electric car that employs a cascade of buck converters and symmetrical bridge-less power factor-corrected converters. Both converters are increasingly common in the industrial sector thanks to their high efficiency, low price, and small size. The entire battery charging mechanism is made substantially more efficient by integrating the two converters. Furthermore, at any input voltage, this charger's design can deliver the correct battery current and voltage without ripple. In order to achieve a unity input power factor and zero input current harmonic distortion, the proposed control approach employs duty ratio feed-forward control technique in both the current and voltage control loops. In addition, a phase-locked loop (PLL) block establishes the current loop's reference, producing a pure sinusoidal input current despite the input voltage waveform's distortion. The viability and utility of the suggested approach are demonstrated using simulation and experimental data with an 110V/60Hz ac line input and a 1.5kW-72V dc output of the battery charging system.

The country's population is growing, and as a result, so is the demand for electricity. The amount of energy squandered is also rising in many different ways simultaneously. The primary approach is to regenerate this energy in a form that can be used. In this project, human footsteps are used to generate electricity, which is then used to recharge the battery. A battery that can be used to charge electronic gadgets stores the power. The Atmega 328 processor powers this system, which also includes an Arduino IDE, an RFID sensor, a USB cable, and an LCD. The system goes into registration mode when we turn it on. We are able to add three users. After each user has logged in, the system prompts them to swipe their cards and connect their chargers. Every user initially receives 5 minutes of charging time by default.

Despite efforts to minimize and reduce it, traffic congestion has been one of the main problems that most metropolises are experiencing. One of the biggest issues facing engineers, planners, and policy-makers in metropolitan settings has been traffic congestion. The proposed approach for managing traffic is based on machine learning methods. To improve traffic control and management, a robust and trustworthy traffic monitoring system is essential. The detection of vehicle traffic a crucial component of the surveillance system. The traffic flow aids in management and control, particularly when there is a traffic jam, by displaying the traffic situation at regular intervals. A traffic surveillance system for vehicle counting is proposed by the proposed system. The suggested technique processes the image and classifies the vehicle using an SVM algorithm, whereas the YOLO-5 system uses convolution neural networks (CNN) to recognise objects in real time. The results of the experiments demonstrate that the suggested system is capable of offering accurate information for traffic surveillance in real time. The use of machine learning techniques helps to lessen traffic and congestion. Additionally, this method lessens the need for human labor when continuous monitoring is used.

There is a very steep increase in heart stroke at the early age, we have to find out something that will help us to detect the symptoms of heart disease at the starting age and prevent people from finding out about their disease at the last stage. It is not an easy task for a common people to go to hospital frequently and go through costly tests which include ECG and for the same reason we should have some software which is easily accessible and cheap and time saving in predicting the heart disease. So, we plan on develop a website application which will predict the heart disease with the help of symptoms and different body parameters which relates to heart. So, we use machine learning algorithm preferably naïve base algorithm which gives the most accurate result and hence we have used it in the proposed model.

There are various methods to avoid fraudulence in the voting system. The main aim of the biometric voting system using LABVIEW is to improve the Indian voting system. By implementing the Bio-metric process, we can make the polling process more secure and efficient than the existing one. Every resident of India has a right to cast a vote and to utilize this right the election process should happen fairly and efficient. The election commission of India has a prime responsibility to implement the most efficient methods for voting. The political race commission of India has various sorts of casting a ballot framework; for example, emit expressive dance paper technique, and presently Electronic Voting Machine ( EVM’s) and Voter Verified Paper Audit Trail (VVPAT) casting ballot machines. The ongoing democratic framework has EVMs which can be hacked without any problem. There are many methods adopted to avoid malpractices. Here we’re using Global System for Mobile communication (GSM) module for sending messages to the citizens who cast their vote, that “your vote cast successfully, thank you," and also send alert notifications to assigned police in charge near the polling booth if the voter tries to reattempt to cast a vote. The person at the station must put their finger on the digits so that the veteran can get the digit identification card. This data is sent to the LABVIEW Control Unit for verification. The LABVIEW control unit receives and compares data from the reader with data already collected during voting registration. Individuals will be allowed to vote if information related to fingerprint information is contained in the database. Individual votes are prohibited unless a warning message is displayed in the dialog box.

In this study, we show how input power, terminal voltage, and efficiency changes as a function of load current. In this situation, we've chosen three scenarios they are- Coil connection in Parallel Coil connection in Series Two Winding Transformer Here, we have connected the coils of a single-phase transformer in series and parallel, then observed the transformer's loading as an autotransformer and as a two-winding transformer. It is essential to comprehend the instant polarities of the secondary terminals in relation to the primary in order to properly connect the winding.

Electrical task balancing counts have advanced fundamentally, from distorted figurings like initially start things out serve, to bio-impelled and AI estimations like Q-learning and genetic computations. The main objective of any task altering computation is to constrain the number of execution cycles expected to absolutely and satisfactorily execute a given course of action of endeavors. During this work, we reviewed the unmistakable endeavor altering count which relies upon an improved differential headway (IDE) strategy. The proposed assessment endeavors to accept the shifted nuances of Electrical endeavor modifying, which join task length, task satisfaction time, virtual machine arrangement, and task cut-off time. Also, the arranged estimation is shaped holder all around arranged, which ensures that the scheduler works satisfactorily on a compartment circumstance to upgrade the efficiency of the electrical plan. We study these systems and discover the most straightforward one for assessment and review.
