Abstract
Present day guided weapon systems, especially tactical class missiles use RF seeker, for target tracking towards terminal engagement. The seeker system including its antenna assembly will be onboard the missile. Due to the missile trajectory corrections, the seeker antenna pointing to the target may get disturbed resulting in track loss. To avoid this track loss, it becomes necessary to stabilize the antenna system in two planes. The fundamental role of stabilization loop in seeker application is to precisely follow the angular rate of the target. In order to achieve this requirement, it is essential to highly isolate the gimbaled antenna from the missile body motion due to the maneuvering of target or low frequency vibration during flight. However, the isolation ratio and stability margin of stabilization loop adopting the gimbaled platform with both low stiffness and heavy inertia are limited by mechanical characteristic such as low resonance frequency and its high magnitude. The selection of proper feedback sensors, modeling of the total system are key features of this project. In the end, the performance and the stability of designed stabilization loop are demonstrated using simulation in both frequency and time domain. The Hardware for the system is under realization by the Industry. The whole scheme is simulated in MATLAB off-line for this project.
Keywords: Missile, RF seeker, Track loss, Stabilization loop, Angular Rate Command, Bore-Sight Error, Maneuvering and Gimbaled Platform.

Modelling & Simulation of PV Module Connected with Three-Port DC ConverterDr. Amarjeet Singh
Of the world’s electricity is being generated through conventional sources of energy like coal and atomic energy. People have realized the dire effect of using these fuels, and the amount of CO2 being released into the environment. There has been a shift in emphasis towards cleaner ways of generating electricity in recent years. Solar energy is abundantly available and the cleanest renewable energy source available in the world and is ready to use for a variety of applications, such as the generation of electricity for residential, commercial, or industrial consumption and have become very competitive solutions. It can be seen that there is trend of solar photovoltaics (PV), which has seen rapid growth over the years. The increasing trend of adopting PV system allows consumers to be known as producers or “Prosumers”.
This report evaluates how solar PV can be used in combination with a battery bank along with three port converter to fulfill the requirement. Power production from PV cannot be consistent due to factors like the weather although The main benefits of solar power are that it can be easily installed cost of generation is low as there is no requirement for fuel and require very little maintenance Distributed maximum power point tracking (MPPT) and autonomous are achieved with the proposed configuration. The input-port of each TPC is connected to an independent PV energy source to achieve individual MPPT, and the output-ports of these TPCs are connected with load. Fully modular design is achieved by using Simulink/matlab.
DESIGN AND MODELLING OF STANDALONE HYBRID POWER SYSTEM WITH MATLAB/SIMULINKMichael George
This paper presents a standalone hybrid power system using wind/PV/diesel/Battery energy system with Matlab/Simulink environment. PV & Wind are the primary power sources of the system and battery is used as a backup for long run application. Here we have also compare the performance of PV/Wind/Battery connected system with PV/Wind/Diesel connected hybrid power system. The most frequently used renewable energy sources are those consisting of PV module and/or wind Turbine with/or Diesel generator, and some energy storage or backup system.
Energy crisis are of special attention now-a-days. In this project presents a new system configuration of the front-end rectifier stage for a hybrid Hydro/wind/photovoltaic energy system. This system allows the three sources to supply the load separately or simultaneously depending on the availability of the energy sources. In household power generation wind and solar are the general hybrid energy options, which are used. But the overhead water tank is one of the neglected energy generation sources which are available in normal household and commercial places. In today’s world each and every source of energy has to be utilized. Therefore we are trying to use the stored energy in overhead water tank for power generation. Solar and Wind energy will contribute major part of power generation. Generated power will be stored in the battery which sources power to inverter and inverter to load. It gives us multiple sources of energy and also helps us to recover some amount of energy which is stored in overhead water tank.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
