A NEW APPROACH TO DTC METHOD FOR BLDC MOTOR ADJUSTABLE SPEED DRIVEScscpconf
This paper proposes a new approach to direct torque control (DTC) method for brushless direct current (BLDC) motor drives. In conventional DTC method, two main reference parameters are used as: flux and torque. In this paper, the new approach has been proposed to improve the BLDC motor dynamic performance. A main difference from the conventional method of it was that only one reference parameter (speed) was used to control the BLDC motor and the second control parameter (flux) was obtained from speed error through the proposed control algorithm. Thus, the DTC performance has been especially improved on systems which need variable speed and torque during operation, like electric vehicles. The dynamic models of the BLDC and the DTC method have been created on Matlab/Simulink. The proposed method has been confirmed and verified by the dynamic simulations on different working conditions.

The document discusses three types of electric braking for DC motors: dynamic braking, plugging braking, and regenerative braking. Dynamic braking involves disconnecting the armature from the power supply and connecting it to an external resistor, causing current to flow in the opposite direction and slow the motor. Plugging braking rapidly changes the armature connection to reverse polarity, generating braking torque. Regenerative braking uses a chopper to allow the motor to act as a generator, returning energy to the power supply. Examples of calculations for braking power, time, and other parameters are also provided.

Efficiency analysis of hydraulic power steering systemLaukik Raut
Hydraulic assisted power steering
system is a high bandwidth servo with stringent
performance requirements on accuracy,
reliability, and cost. Design of such a system can
be best achieved by using a validated and user
friendly computer simulation program.
Hydraulic integrated power steering ( HIPS )
program has been developed using basic concepts
from science and engineering. HIPS provides a
design and test environment for the integrated
steering and suspension system subjected to
disturbance forces, which may be induced by
pump flow oscillations and tire loads. Two realworld automotive hydraulic steering systems are
simulated with HIPS. The simulation results
agree closely with the dynamometer test results.
The application of HIPS for design optimization
is also demonstrated.

IRJET- Kinematic Structure and Reenactment of an Adaptable Valve Lift System ...IRJET Journal
This document summarizes a research paper that proposes a new "TRI-LOBED-CAM" valve actuation system for internal combustion engines. The system aims to overcome limitations of fixed cam and variable valve timing systems by variably controlling valve lift based on engine operating conditions like load and speed. It describes how variable valve timing can improve fuel efficiency up to 20% by making valve lift a variable function of crankshaft angle. However, issues with noise and wear occur in variable valve timing systems due to high valve contact speeds during opening and closing. The proposed TRI-LOBED-CAM system would pivotally adjust camshaft position to achieve minimum, medium, and maximum valve lift for low, middle, and high engine loads
Regeneration in Variable Frequency Drives and Energy Saving MethodsIRJET Journal
This document discusses methods for regenerating energy from variable frequency drives to save costs. When an induction motor decelerates, it generates electricity that is normally wasted as heat through braking resistors. Regenerative converters can return this energy to the grid instead. Three types are described: regenerative converters use PWM to feed energy back through the supply line; sinusoidal PWM converters regulate voltage while improving power quality; and matrix converters directly convert AC to AC with minimal components. Matrix converters integrate regeneration and driving but have limited voltage transfer. Regenerative converters provide significant utility cost savings, especially for applications with frequent braking like cranes or elevators.
1) The document discusses isolated and non-isolated bi-directional DC/DC converters for use in a Formula Hybrid electric vehicle.
2) It evaluates two isolated uni-directional converter topologies and discusses the working principles of three bi-directional converter topologies.
3) The goal is to determine the most efficient topology by conducting a comparative analysis to minimize losses.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
