Title: Design and development of web based embedded controller for electric drives.

The objective of this research work is to design and develop a web based embedded controller for a PV powered low cost, batteryless electric drive. The Maximum Power Point Tracking (MPPT) system is implemented with current fed full-bridge boost dc-dc converter, to extract maximum power from the solar PV array using hill climbing algorithm. This algorithm is simulated in MATLAB/SIMULINK and implemented with microcontroller. This work also compares vector control using PI controller, classical Direct Torque Control (DTC) using Space Vector Pulse Width Modulated (SVPWM) and Fuzzy Logic based Direct Torque Control (FL-DTC). The controllers are designed and simulated with MATLAB/SIMULINK and implemented as embedded controller with Field Programmable Gate Array (FPGA) processors. The advantage of Fuzzy Logic Controller (FLC) is a linguistic controller and does not require a precise and accurate mathematical model of the induction motor drive. The major problem in a DTC-based motor drive is the presence of ripples in the motor-developed torque and stator flux.One of the methods to reduce ripples in torque and flux with less complexity and cost is space vector modulation strategy in DTC Method.

A fuzzy logic based direct torque control of induction motor has been carried out in distributed client server architecture to remotely simulate DTC induction motor dynamics by executing a simulation program on a server through the internet in distributed client-server architecture. During storage and transmission, the information is exposed to unauthorized entities and hence adequate security measures are built around the information system using Advanced Encryption Standard (AES) algorithm. The remote access and monitoring of electric drives can be done through the network and web browser. Design of different architectural models for real time monitoring of electrical drive system for the client / server model i.e., multi-tier architectural model for electrical drive system and the performance analyses are carried out in distributed environment.

Title:  A Low frequency AC to high frequency AC inverter with built-in power factor correction and soft-switching.

This  project  deals  with  a  full  bridge  AC – AC inverter for high frequency power distribution with power factor correction stage controlled by a unified controller. The proposed inverter has the following features.

1. Load  independent  output  voltage  with constant frequency and very low total harmonic distribution (THD)

2. Soft switching of the full bridge switches for a wide range of input voltage and load conditions

3. Low DC bus voltage 

4. Simple control and cost effectiveness for the power factor correction stage

CENTRE FOR PROFESSIONAL DEVELOPMENT EDUCATION:

Title: Budget Accounting System:

    The Software has been developed to compile monthly and Annual Accounts in the Centre for Professional Development Education, Anna University by creating various modules having separate provisions for receipts and payments of voucher transactions done under various departments. Various head of accounts have been added such as computer purchase, machinery and equipments purchase, furniture, lab consumables, printing and stationary, office expenses etc, for each departments and for autonomous centre in Anna University where budgets has been allocated to each departments / centres in Anna University and monitoring the expenses under each head of accounts with respect to the receipts collected to each department. Various reports were generated based on date-wise, month-wise, financial year-wise and department/ centre-wise and annual accounts can be generated for the particular year and the budget can be prepared for the next financial year.

Title:  Digital Library Project:

My job  responsibility involves  scanning  the palm leaves, IEEE Journals and Books, processing it  and digitizing in various formats instructed  to  me  so  as to insert / retrieve the same from the database called  as “Searchable Database”. The  Digitizing  regarding  Palm Leaves  and IEEE Journals is being done for IISC, Bangalore and Anna University to enable  Research  Scholars  to  avail  the source  for their research work. Moreover digitizing of Ph.D, thesis is done to University library so as the research students of the University can utilize the service available for their Reference. Digitization of Syndicate resolutions is  being done for  confidential  matters  related  to Anna University by the members of the Syndicate and the Registrar,  Anna  University  through  The  Director,  CPDE  for  the  forthcoming suggestive operational reference.
