Design and Modeling of I2C Bus Controller
Abstract
This project is concerned with the design of I2C bus controller and the interface between the I2C devices i.e. microcontroller (AT89C51) and EEPROM (AT24C16). The I2C is a two wire serial protocol. Hence I2C components can be interfaced by using only two lines. First one is serial data (SDA) line and second is serial clock (SCL) line. The design architecture consists of a master controller and a slave. The master generates the START condition when SCL is HIGH and SDA is having a transition from HIGH to LOW. Master also generates STOP condition when SCL is in HIGH and SDA is having a transition from LOW to HIGH. Beside these two functions master also transfers and receives data to/from different slave devices. When master transmits data to slave receiver then it is known as WRITE mode of operation and when master receives data from slave transmitter then it is known as READ mode of operation. The microcontroller and EEPROM are interfaced through I2C bus. Data send, read and write particularly these operations are carried out and the behavior of I2C protocol is examined. The I2C master controller is designed in verilog HDL. By describing the design in HDL, functional verification of the design can be done early in the design cycle. Since designers work at the high level language, they can optimize and modify the design module until it meets the desired functionality. The test bench program has to be developed to test the design module. The test bench gives the input to the design module & verifies the outputs. The test bench has to be written in such way to check the design module in all possible conditions.
Baseband Processor Design of Multi-purpose RFID Tag
Radio frequency identification has found ubiquitous usage in today�s industry. Object identification and tracking, supply chain management, anti-theft and fraud systems are just some of the uses RFID tags find in today�s market. As the RFID technology competes with other technologies present in the market, a large amount of research has been undertaken in order to optimize the performance and cost factors of the readers and tags involved in the RFID system. Various implementations on different devices such as ICs and CMOS System on Chip (Soc) have been tried out. FPGAs are also being considered as a potential target device for implementing RFID systems. This project aims at the design of an FPGA implemental RFID Tag processor design for the purpose of base-band signal processing. A new architecture has been proposed and implemented for this processor. This architecture takes into consideration the flexibility of the entire system with the help if independent sub modules. Also, the suggested architecture has taken into consideration the creation of an innovative single tag for multiple purposes which can interact with various types of readers and convey the required information to each one of them. The RFID tag has been designed in accordance to EPCglobal Class1 Generation2 standard for operation in the range of 860-960 MHz in the air interface. The design of the tag components has been done with the help of XILINX and the verifications and analysis with ModelSim.
PLC Implementation of Supervisory Control for a Dynamic Power Flow Controller using a Modular Approach
Abstract
Dynamic Power Flow Controller (DPFC) provides steady-state and dynamic power flow control for power lines and is considered as a Flexible AC Transmission System (FACTS) controller. This paper deals with control of a standard DPFC using a Discrete Event System model. The Supervisory Control of DES has been used to implement Modular supervisors for the DPFC. Despite the fact that the SCT is well consolidated, with a large number of publications focusing on the theoretical aspects, the industrial application is unknown. It is mainly due to the complexity of the theory. The numbers of states and events to be controlled are very large even for the seemingly simple systems. In recent years, a model for modular approach to the Supervisory Control for performing the formal synthesis of Supervisors has been proposed. Programmable Logic Controllers are used for the physical implementation of the controllers. Some problems in physical realization of Supervisors in PLCs are dealt with.
Designing a real time embedded controller using data acquisition system for a DC motor speed control
Abstract
Speed of a DC motor varies proportional to the input voltage. With a fixed supply voltage the speed of the motor can be changed by switching the supply on and off so frequently that the motor notices only the average voltage effect and not the switching operation. This project focuses on controlling the speed of a DC motor using PWM technique (varying duty cycle of a square wave) and Data Acquisition Systems.
Virtual instrumentation is defined as the combination of measurement and control hardware and application software with industry-standard computer technology to create user-defined instrumentation systems. A DAQ card is designed and used for speed control in this project.
Analysis of ECG signal for Detection of Cardiac Arrhythmias
Abstract
Electrocardiogram (ECG), a noninvasive technique is used as a primary diagnostic tool for cardiovascular diseases. A cleaned ECG signal provides necessary information about the electrophysiology of the heart diseases and ischemic changes that may occur. It provides valuable information about the functional aspects of the heart and cardiovascular system. The objective of the project is to automatic detection of cardiac arrhythmias in ECG signal. Recently developed digital signal processing and pattern reorganization technique is used in this project for detection of cardiac arrhythmias. The detection of cardiac arrhythmias in the ECG signal consists of following stages: detection of QRS complex in ECG signal; feature extraction from detected QRS complexes; classification of beats using extracted feature set from QRS complexes. In turn automatic classification of heartbeats represents the automatic detection of cardiac arrhythmias in ECG signal. Hence, in this project, we developed the automatic algorithms for classification of heartbeats to detect cardiac arrhythmias in ECG signal. QRS complex detection is the first step towards automatic detection of cardiac arrhythmias in ECG signal. A novel algorithm for accurate detection of QRS complex in ECG signal is proposed in chapter 2 of this project. The detection of QRS complex from continuous ECG signal is computed using autocorrelation and Hilbert transform based technique. The first differential of the ECG signal and its Hilbert transformed is used to locate the R-peaks in the ECG waveform. The autocorrelation based method is used to find out the period of one cardiac cycle in ECG signal. The advantage of proposed method is to minimize the large peak of P-wave and T-wave, which helps to identify the R-peaks more accurately. Massachusetts Institute of Technology Beth Israel Hospital (MIT-BIH) arrhythmias database has been used for performance analysis. The experimental result shows that the proposed method shows better performance as compared to the other two established techniques like Pan-Tompkins (PT) method and the technique which uses the difference operation method (DOM). For detection of cardiac arrhythmias, the extracted features in the ECG signal will be input to the classifier. The extracted features contain both morphological and temporal features of each heartbeat in the ECG signal. Twenty six dimension feature vector is extracted for each heartbeat in the ECG signal which consist of four temporal features, three heartbeat interval features, ten QRS morphology features and nine T-wave morphology features. Automatic classification of cardiac arrhythmias is necessary for clinical diagnosis of heart disease. Many researchers recommended Association for the Advancement of Medical Instrumentation (AAMI) standard for automatic classification of heartbeats into following five beats: normal beat (N), supraventricular ectopic beat (S), ventricular ectopic beat (V), fusion beat (F) and unknown beat (Q). The beat classifier system is adopted in this project by first training a local-classifier using the annotated beats and combines this with the global-classifier to produce an adopted classification system. The Multilayer perceptron back propagation (MLP-BP) neural network and radial basis function (RBF) neural network are used to classify the cardiac arrhythmias. Several experiments are performed on the test dataset and it is observed that MLP-BP neural network classifies ECG beats better as compared to RBF neural network.
FPGA Implementation of digital controller for shunt active power filter to reduce harmonics and reactive power
Abstract
Most of the pollution issues created in power systems are due to the non-linear characteristics and fast switching of power electronic equipment. Power quality issues are becoming stronger because sensitive equipment will be more sensitive for market competition reasons, equipment will continue polluting the system more and more due to cost increase caused by the built-in compensation and sometimes for the lack of enforced regulations. Efficiency and cost are considered today almost at the same level. Active power filters have been developed over the years to solve these problems to improve power quality. Among which shunt active power filter is used to eliminate and load current harmonics and reactive power compensation. The active power filter (APF) is implemented with PWM based current controlled voltage source inverter (VSI). This VSI switching signals are generated through proposed three-level hysteresis current controller (HCC) that achieves significant reduction in the magnitude and variation of the switching frequency; it is indicating improved performance compared to 2-level HCC. The shunt APLC system is modeled and investigated under different unbalanced non-linear load conditions using MATLAB programs. The simulation results reveal that the active power filter is effectively compensating the current harmonics and reactive power at point of common coupling. The active power line conditioner system is in compliance with IEEE 519 and IEC 61000-3 recommended harmonic standards. Due to non-linear characteristics the load current gets distorted which causes undesirable effects like heating, equipment damages, EMI effects etc. in power network. The active power filter (APF) is the best solution for eliminating the harmonics caused by the non-linear loads. This work presents the three-phase four-wire active filter for power line conditioning (PLC) to improve power quality in the distribution network and implementation of a digitally controlled APF.
Designed in Hardware Description Language (VHDL or VERILOG), the controller becomes independent of process technology. Synchronous reference frame is used for generation of reference current. PI currents algorithm and hysteresis current controller (HCC) together is written in VHDL code and is implemented using FPGA platform. Various simulation results are presented under steady state and transient state condition and performance is analyzed. Simulation results obtained shows that the performance of three phase system with APF is found to be better and digital controller add a new aspect for the controller from low cost, high speed and hardware implementation point. PWM and hysteresis based current control is used to obtain the switching signals to the voltage source inverter (VSI).
Radio Frequency based wireless remote controlled digital camera with high Intensity LED flash lamp
The purpose this project is to control and monitor the Wireless Video Camera and its direction using a RF remote. The video images thus captured can be seen live on TV. It is a low cost surveillance system used to monitor a larger area. The camera and its direction can be controlled by a unique wire less remote.
Here the purpose of LED is to serve as a light source for the camera when ever it is operated in low intensity, the wording here means that the LED should again be controlled by controller such that it takes an input from a light sensor and glows the LED intellectually if it feels the light available in the surroundings is not sufficient enough to catch the images. By this we can make sure that we also save power to some extent.
The major challenge here is we should think twice while programming to make sure that we are able to process both the tasks (camera direction and LED glowing) simultaneously with out any delay.
