Agriculture is considered as one of the traditional occupations in India, due to the fact of specialization and skills we possess. Ancient farmer used their advanced skills and techniques to yields production from various sources, but in today's scenario farmers are striving hard to cultivate the land and yield the production. The farmers today are not the same as yesterdays and the farmers present...
Exoskeletons are designed to assist and enhance the human beings ability to move with lesser efforts. The estimation of torque required at joints of an Exoskeleton is having a prior importance, to choose the right actuator. We have used motion analysis software to measure the parameters of motion during sit to stand phase (STS) and back to sit phase (BTS) and the torque is calculated using Lagrangian...
The multiplicity of transactions frequently leads to the conditions where the operating zone will not remain secure in the field of emerging electric power systems. In the system of power security advancement, the highly Flexible AC transmission systems (FACTs) controllers will play a prime role. But because of large scale capital investment it is required to locate the FACTs controllers in the power...
This paper presents a comparative review of three different three phase inverter topologies namely the PWM Inverter, 180 Conduction Inverter, and the Multilevel Inverter. The comparison between these topologies is carried out on the basis of percentage of Total Harmonic Distortion (THD) that exists in the output voltage. In this work, each inverter operates at the 100V DC input. The complete analysis...
The analysis of two, three and five-level diode-clamped inverter fed Interior Permanent Magnet Synchronous Motor drive for Electric Traction application is presented. The drive has been controlled by Direct Torque Controlled Carrier Based Space Vector Pulse width Modulation (DTC-CBSVPWM). DTC is a precise controller for permanent magnet synchronous motor (PMSM) owing to its robust and fast torque...
A time-driven pole placement based Memory Less State Feedback Controller (MSFC) has been designed using the Linear Matrix Inequality (LMI) to control a plant over an network under variable latency (jitter) and data-loss. This Networked Control System (NCS) has been formulated as an Asynchronous Dynamic System (ADS) with rate constraints. The pole placement based controller has been derived to place...
Present day launch vehicle telemetry systems require high resolution, precise data acquisition systems to accurately reveal the system performance in extreme environments. In order to achieve high resolution these data acquisition systems invariably use sigma delta ADCs. With the advent of IC technology it has been possible for chip manufacturers to integrate instrumentation amplifiers and Digital...
Internet of things (IoT) integrate the technologies such as sensing, communication, networking and cloud computing in wide range monitoring zone. For applications of IoT, the most appropriate monitoring network is wireless sensor networks (WSN). It is most important to develop energy efficient cluster head (CH) selection scheme to increase the network lifetime of WSNs. It is most crucial to save the...
This paper provides the study of a new emerging energy technology. In order to provide clean and reliable power, the renewable and non — renewable power resources has to integrate as a microgrid. The integrated system comprises distributed generation units, power storage units, electrical loads and control systems for an efficient management, the management system of a microgrid must provide a better...
In the wireless world, the devices face a unique challenge of energy scarcity. Unlike the wired systems, there is no continuous wired energy resource available to power the ongoing wireless communication. Instead, the entire system runs on wireless batteries. Taking a step further in this field, the concept of energy harvesting is introduced a while ago. This paper combines the concept of harvesting...
The main aim of this paper is to reduce the distortion produced in the output side of the AC mains of electronic ballast. The paper implies design of electronic ballast (EB) for compact fluorescent lamps (CFL) by replacing the conventional electronic ballast circuitry with improved SMPS and inverter topologies. Here zeta converter (DC/DC converter) is implemented as power factor correction circuit...
This paper deals with fault diagnosis & Protection of induction Motor. A various types of faults are occurred in the I.M such as over voltage, under voltage, over current, single phasing. The proposed system detects the various types of faults by monitoring stator current of induction motor. To predict and protect the type of fault occurs in induction motorA fuzzy logic with PIC microcontroller...
This paper presents the simulation for sensorless operation of BLDC motor drive with speed control, designed for Air conditioners. As the motor starts to rotate back EMF is obtained from the motor terminals using a voltage divider along with a low pass filter. Control pulses for inverter are generated based on the zero crossing of back EMF. The results have been validated in Matlab Simulink platform.
Rehabilitation engineering for tremor disorders is a thriving field of study in the present day with our ever-growing understanding of neuro-degenerative disorders. However, these technologies are often far from being commercially viable, or economically accessible to the affected populace. As such, the following paper attempts to functionalize the simple mechanism of a viscous biomechanical orthosis...
This paper concentrates on the control of the pH value of a liquid using Ph Neutralization plant and to control the liquid level using a Split Range plant. The control methods used are PID control and FUZZY control. These two controllers are subjected to prototypes of both the process plants. The results are presented and the best controller is suggested. The whole programming is done using LabVIEW...
In this paper, a non-integer (fractional) order controller namely tilt integral derivative controller has been introduced as supplementary controller in automatic generation control (AGC) of a two-area power system. Generally, classical control approach such as PI control and PID control has been most widely used in AGC scheme, but due to increase in complexity of the power system, the performance...
This paper presents an iterative pre-filtering based algorithm for Wiener system identification by using bilinear parameterized formulation. This method assumes the invert ability of the non-linearity involved in the modeling of wiener model. In addition, the output of the linear block is corrupted with noise signal resulting a model with correlated noise disturbance. The least square solution fails...
