In this paper, the design of software module using ‘schematic’ for Xilinx FPGA (XCV50-4-CS144) based protection unit for synchronous generator is presented. The tools used for building and testing the software modules are Xilinx Foundation Series 3.1. Before verifying the design on FPGA the complete design is simulated using Modelsim Simulation tool. A test simulation is written where, the set points speed can be changed for the motor. It is observed that the motor speed gradually changes to the set speed and locks to the set speed. The synchronous generator protection unit can carry out all necessary generator protective functions. The synchronous generator protection unit is easily re configurability features rather than high accuracy and processing speed for generator signals. In this paper I present compact system in one unit and multiple generator protections.

This paper presents new numerical injection model of Inter Line Power Flow Controller (IPFC). Indeed, linear model of voltage source inverter of IPFC is improved to estimate steady-state operation of IPFC as well as Static Synchronous Series compensator (SSSC) in power system. The proposed method estimates the effect of IPFC on active and reactive line power flow with SSSC for three modes such as resistive, capacitive and inductive. Thus, it is recommended that the proposed technique can be applied for prediction of initial injected voltage and its phase angle of IPFC and SSSC for their modeling in real system. The tested system for simulation is based on IEEE two machine systems. The result of simulation and the numerical analysis shows the robust accuracy of obtained estimation of IPFC and SSSC.

Manual place-and-route method in handling structured datapath placement usually requires long design cycles and high design cost. To minimize the human effort in placing cells, Integrated Circuit Compiler (ICC) has been introduced to help user in automate place and route with its powerful embedded placement algorithm. A structured datapath design contains repeating dataflow logics, which is highly regular and structured. Currently, the automated placement tool from ICC is incapable to place structured datapath design effectively. This paper describes an approach for customizing the ICC tool to automate structured datapath placement in Very Large Scaled Integrated (VLSI) layout and achieve better placement quality. An algorithm named structured datapath relative placement (SDP-RP) is proposed to obtain the relative placement (RP) of a SDP design. From the initial placement generated by ICC, structured registers are extracted. Connectivity of all the related cells is traced to form the RP groups for each structured pattern. The relative placement constraint file containing RP groups is generated and read by ICC tool to improve placement optimization process. The implementation of this algorithm in ICC placement flow for SDP design has achieved structural placement with 2∼24% timing improvement and cell counts reduction.

This paper proposes a robust decoupling current control system to magnetic saturation phenomenon using an extended flux observer for synchronous reluctance motors (Syn-RMs). SynRMs possess considerable magnetic non-linearity, which gives rise to the difficulty in highly accurate decoupling current control. Hence, to realize robust decoupling current control system to magnetic saturation phenomenon, inductance profiles need to be found at various current points for driving SynRMs. This method, however, requires to prepare highly accurate look-up-table of inductances in advance. This paper proposes robust decoupling current control system to magnetic saturation phenomenon without the table of inductances. The proposed method employs the extended flux observer for the realization of robust decoupling control. In addition, the extended flux observer suitable for proposed method is discussed by analyses of bode diagram. Finally, experimental results show the feasibility of the proposed method in this paper.

Multi-User navigation within an environment with the aid of 3D mobile support provides end users with additional mobility thought and improves mobility services' efficiency. A necessary approach of using mobile device for navigation aid is to display only a section of the view-front and to let users control the portion shown by conceptually moving on the orientation. There is a need for multiple users to be able to interact with themselves when they are within an environment and navigating with the aid of 3D mobile devices support, in order to meet-up with an appointment or to be aware of the locations of each other. Unfortunately, the predominant 3D mobile navigation system does not provide multi-user interactive services. Users cannot be aware of other users navigating within same environment using the same system on their mobile devices at the same time. This paper presents multi-user 3D mobile navigation system for providing multiple user awareness. The analysis of the results provides a unique visualization of multiple users using mobile devices to help them navigate to a target location by being aware of their whereabouts.

This paper presents theoretical investigations into the dynamic characterisation of a two dimensional gantry crane system. A dynamic model of the system is developed using Euler-Langrange formulation. Simulation exercises are performed in Matlab with three different control strategies; LQR, DFS and PD controllers and then the results are compared with uncontrolled system. To study the effects of payload weight on the response of the gantry crane system, the results are evaluated with different payload weight in the algorithm. Results achieved from simulation work are shown in time and frequency domains. Performance of the feedback controllers in minimizing the sway angle is examined in terms of time response specifications and magnitude of sway. Finally, a comparative assessment of different payload weight to the system performance is assessed and discussed.

In this paper, a CMOS retinal rotational sensor for clockwise/counterclockwise detecting and velocity measuring is proposed. The proposed chip is attractive due to the fact that analog image processing circuits within a pixel are implemented by digital circuits. It can be integrated robustly and compactly. Based upon the device parameters of 0.35 µm 2P4M CMOS technology with 3 V power supply, all the functions and performance of the proposed CMOS retinal rotational sensor for clockwise/counterclockwise detecting and velocity measuring are successfully tested and proven through SPICE simulations. The chip area is 1.792 × 1.795 mm2. The proposed chip is suitable for rotational image detecting and velocity measuring.

Low cost multiple input multiple output (MIMO) Wireless Data Acquisition System (WDAS) for long range operation has been developed, simulated and implemented. The reference input and output measurement circuits for various sensors to measure strain, vibration and temperature have been designed, and integrated. Low cost microcontroller is used to process and condition the signals that are acquired from measurement circuits. The sequential logic is used to capture and transmit the measurement signals using single receiver and transmitter pair instead of conventional MIMO antenna systems. This reduced the cost significantly. The wireless communication has been established and data acquired from sensors within 20 mile of distance. The acquired data is then processed at the base station using data acquisition system (DAS). The system that is developed can be used for structural health monitoring, or medical applications in rural areas where access is difficult.

While designing all the attributes of a Hybrid vehicle, the most important factor is the fuel economy. Reduced aerodynamic drag and light weight vehicle chassis are major factors for improving the fuel economy. The series hybrid vehicle designed utilizes gasoline to generate electricity which is then stabilized and stored in the super capacitor banks. This stored electrical energy is then used for driving the brushless DC motors. A specially designed control system regulates the transmission of electrical energy through a automatic voltage regulator (AVR), programmed for controlling the output of the generator and the super capacitor banks. This results in improved efficiency and reduction in mechanical losses.

Magnesium Oxide, MgO is inorganic material with wide band gap (7.8eV) and suitable to be used as dielectric layer. Due to its chemical and structural properties, MgO also can be used as template to prepare ferroelectric thin film [1–3]. In this work, MgO thin films with different molar concentration from 0.1M to 1M were prepared using sol-gel spin coating technique. Magnesium acetate tetrahydrate, ethanol and nitric acid were used as precursor, solvent and stabilizer respectively. The MgO thin films were deposited on the glass substrate and subjected to electrical and structural characterizations. Both electrical and structural characterizations were performed using two point probes (BUKOH KEIKI-EP2000), surface profiler (Veeco) and atomic force microscope respectively. The experimental results show that the thin films resistivity increased from 5.09 ×103 Ω.cm to 2.33 ×104 Ω.cm as the precursor molar concentration increased. The MgO films with 0.4M was observed to be the best MgO films to be used as dielectric layer due to its electrical and structural properties which are uniform, non-porous and small particle size around 43nm.
