    Leaves Recognition System
    (2015-12-21T08:47:49Z) Afshiya, Suman; Ankit, Kumar; Buddareddy, Tejaswini; Saranya, G
    Plants are essential part of nature and in people's lives. They are the ultimate source of food and metabolic energy for nearly all animals, which cannot manufacture their own food. Thus the study of plants is vital because they are a fundamental part of life on Earth, and generate the oxygen and food that allow humans and other organisms to exist.A digital plant identification system can be used for quick characterization of plant species without requiring the expertise of botanists, thus atomizing their task. The proposed system ”Leaves Recognition System” is aimed to develop a java program to recognize the images of leaves by using previously trained Neural Network. The outer frame (edge) of the leaf and a back propagation neural network is enough to give a reasonable statement about the species it belongs to. The system is user friendly. The user can scan the leaf and click the recognition button to get the solution.

    PV Power System With MPPT Converter Based Vector Controlled 3 Phase Induction Motor Drive
    (2016-07-12T10:48:50Z) Anirban, Mondal; Ankit, Kumar; Brahmanand, Keste; Dhiraj, Prabhakar
    This project is an attempt to develop a portable system in which the pv cells will act as the source and the 3 phase induction motor drive is connected to it. A MPPT controller is used to develop the charger. The MPPT control is developed from the incremental conductance method. The control for the induction motor will need the three phase inverter. The technique called vector control is used to vary the speed of induction motor over a wide range. In the vector control scheme, a complex current is synthesised from two quadrature components, one of which is responsible for the flux level in the motor, and another which controls the torque production in the motor .The Photo Voltaic powered three phase vector controlled induction motor drive system is successfully designed and simulated using MATLAB SIMULINK.

    Speed Synchronization of Multiple Motors in Textile & Steel Mills

    The aim of this project is synchronization of multiple motors using wireless technology. This project uses radio frequency to synchronize motor speeds. This is applicable to many industries like textile mills, steel plants, paper plants wherein all the motors used on conveyor are desired to be synchronized. For example, in textile mills where multiple motors work simultaneously on a conveyor belt to draw clothes, it is essential that all the motors there should run at same speed, so that balanced tension is achieved to avoid clothes getting damaged. In this project motors are wirelessly synchronized to make the differential speed error among multiple motors to zero. One motor acts as transmitter and all the rest as receivers. Thus, if a particular speed is set in the transmitter then all other motors speed would be matched to the same speed of the main motor. The mode of communication is radio frequency. BLDC motors used operate on the basis of PWM control. Each motor has a closed loop feedback mechanism providing RPM reference by a shaft mounted IR sensor arrangement whose output is fed to the controller in the circuit. A display unit displays the full speed and one can enter the desired percentage with help of a keypad to obtain the required speed for all the motors. The pulse width output from the microcontroller would be automatically adjusted to maintain the DC power to the motor such that the entered speed percentage matches the running RPM. The above operation is carried out by using one opto isolator and a MOSFET for driving the BLDC motor duly interfaced from the microcontroller. In various stages of operations motors have to rotate at different speeds, so if we change the speed in transmitting motor then rest of the motors are adjusted accordingly. The whole operation is made simple by using this technology. Manpower and time is also saved in this system. The future works include giving intelligence to the whole system like if any of the motor senses any fault, the whole system will shutdown
