The purpose of this report is to inform the reader of the Senior Design Project lead by 3 students in the Electrical and Computer Engineering department at Western Michigan University. The project is in needed for use within the ECE department as a tool for showcasing to prospective students the attributes of electrical and computer engineering.

At the heart of the project lies an Arduino microcontroller acting as the commanding brain of the system. Its task is to manipulate various types of obstacles throughout the playing field with a goal of delivering a dynamic experience to the player(s). Additionally, a …

Direct Torque Control Of An Lnduction Machine Using Multi-Layer Perceptron Network, Adithya Chandrashekharan

Masters Theses

In conventional direct torque control (DTC) scheme of induction motor (lM), Proportional Integral Controller (PI) is used as the speed controller. PI controller is more suitable in steady state condition and for linear system but both DTC and IM are mostly nonlinear. Multi-Layer perceptron neural network. (MLPNN) controller is more suitable and performs better than PI controller. The switching table of the conventional DTC is replaced by the MLPNN controller. The MLPNN inputs are, the magnitude of the stator flux, torque and the Voltage sectors. Levenberg-Marquardt back propagation technique has been used to train the MLPNN. The output of the …

Lntegration Of Conventional Lithography And Printing Processes As A Key Enabling Technology For Printed And Flexible Sensing Systems, Binu Baby Narakathu

Dissertations

Sensors, which are used ubiquitously in a wide variety of applications, are revolutionizing the already ever-changing world we live in by providing real-time information about our surroundings. This dissertation focuses on the integration of conventional photolithography and printing processes as a key enabling technology for printed and flexible sensing systems.

Initially, an efficient opto-electrochemical sensing system, for the dual detection of heavy metal compounds was successfully developed. A novel microfluidic flow cell, with a reservoir volume of 25 μl, was designed and fabricated using acrylic. An electrochemical sensor with gold (Au) interdigitated electrodes (IDE) on a glass substrate was photolithographically …

Improved Accuracy In Real-Time Rfid Localization Systems Using Kalman Filtering, Benjamin J. Sanda

Masters Theses

The use of Radio Frequency Identification (RFID) has become widespread in industry as a means to quickly and wirelessly identify and track packages and equipment. Now there is a commercial interest in using RFID to provide real-time localization. Efforts to use RFID technology for this purpose experience localization errors due to noise and multipath effects inherent to these environments. This paper presents the use of both linear Kalman filters and non-linear Unscented Kalman filters to reduce error effects inherent to real-time RFID localization systems and provide more accurate localization results in indoor environments. A commercial RFID localization system designed for …

An Enhanced Self-Healing Protection System In Smart Grid: Using Advanced And Intelligent Devices And Applying Hierarchical Routing In Sensor Network Technique, Mohamed Eid Aljahani

Masters Theses

This paper presents a self-healing protection systems were designed using PSCAD software to test and investigate the efficiency of this method. The system was applied on a typical distribution system with loads, buses, and power sources. The availability of advanced and intelligent devices, such as IEDs and PMUs was the trigger to design proficient and accurate self-healing protection systems which are associated with future smart grids. Deploying optimal sensors distributed within the grid could be a suitable method to monitor and control the distribution network. By using a hierarchical clustering communication technique, optimal sensors can work wirelessly and efficiently without …

Opportunistic Service Differentiation And Cloud Resource Management In Support Of Enhanced Vehicular Applications, Mohammad Ali Salahuddin

Dissertations

An integral part of Intelligent Transportation Systems (ITS) are Vehicular Ad hoc Networks (VANETs), which consist of vehicles with on-board units (OBUs) and fixed road-side units (RSUs). Wireless Access in Vehicular Environment (WAVE) offers QoS via service differentiation by using application defined priorities. However, WAVE has unbounded delay and is oblivious to network load and severity of vehicles with respect to their environment. Our context severity metric innovatively enhances WAVE to be sensitive to vehicle and environment interactions. Our novel Opportunistic Service Differentiation (OSD) technique, dynamically readjusts the WAVE packet priorities to improve utilization of lower latency queues, prioritizing packets …

Position Tracking Using Wifi, Nathan Conrad

Honors Theses

Position tracking using WiFi is needed as a more accurate method of intra-building tracking due to Global Positioning System’s (GPS) lack of accuracy in buildings. The main application of this project is to provide a safety system, which may be either tracking employees within a building and allowing them to send an emergency message through a device, or to track objects throughout a building. The devices can send simple messages to a central location. These messages will include position information and which emergency has been selected. The devices consist of two buttons and two LEDs, and with a button press, …

Design Of Hardware Accelerator For Fuzzy Automata Using Dynamic Partial Reconfiguration, Chinh K. Nguyen

Masters Theses

As embedded systems have become more complex and designers are required to develop new products faster while using fewer chips. FPGAs are a good choice because they offer flexibility to design on-chip devices as well as the embedded systems that are reprogrammable and reconfigurable. Today's tougher cost, higher performance, and lower power consumption requirements demand even more efficient design strategies. Dynamic partial reconfiguration (PR) is a good approach to meet these requirements because it extends the inherent flexibility of the FPGA by allowing partial regions of the FPGA to be dynamically reconfigured with new functionality while other applications are still …
