To keep pace with the projected International Technology Roadmap for Semiconductors (ITRS) mainly in terms of low cost, low power and high speed;hole mobility is one of the roadblocks. Hence, many researchers are intensively looking to enhance the hole mobility either by modifying the surface of silicon substrate or by exploring new materials in place of silicon. Thus, in this paper, the electrical properties of strained silicon substrate based MOSFET and Gallium- Antimony (GaSb) based MOSFET are simulated using SILVACO-ATLAS and compared. The band misalignment and occurrence of undesired buried channel in the strained silicon limits the hole mobility, which does not occur in GaSb MOS devices. In spite of retardation of hole mobility in the strained silicon substrate, it is more than the GaSb substrate. Moreover, the GaSb MOSFET turns on at low voltage (-0.1 Volts) and its trans-conductance increases at lower gate voltage range and thereafter it gets saturated. On the other hand, the strained silicon MOSFET turns on at -0.4volts and its trans-conductance saturates at higher voltage range compared to GaSb substrate and its trans-conductance is found to be approximately 4 times than the GaSb MOSFET. Hence, GaSb substrate may work better at low power applications;whereas, the S-Si substrate may be suitable for high hole mobility devices. © 2016 Institution of engineering and Technology.

This contribution deals with modelling of a smart grid with a significant ratio of renewable energy sources. The physical model of an integrated smart grid enables modelling of different control strategies. The grid was designed to test various methods of control, such as an energy efficiency or a utilization of demand response, along with a weather forecast. And it is designed in a way that different variations of the energy transfer occurs. Mainly, it consists of a main grid which is 24 V. Then, there is another part that simulates other backup storage. For example, this storage can be realized as batteries of an electric car. Each part has a different purpose in the grid and it is important to utilize it at the right time. A standard usage is to use only the grid battery and not the unnecessarily relocation of energy. This, however, we can afford only if storage has a sufficient reserve for a specific resource, or if we do not mind that a part of the energy generated by the plant is underutilized. However, we try to avoid it and the grid uses various control principles to prevent this situation. During these transfer may occur many states and one of them is described in this paper. A grid control should maintain approximately the same level of energy in batteries in the real-time. © 2016

EKF-based simultaneous localization and mapping of mobile robot using laser corner pattern matching

Transactions of the Korean Institute of Electrical Engineers 2016年第12期65卷 2094-2102页

In this paper, we propose an extended Kalman filter(EKF)-based simultaneous localization and mapping(SLAM) method using laser corner pattern matching for mobile robots. SLAM is one of the most important problems of mobile robot. However, existing method has the disadvantage of increasing the computation time, depending on the number of landmarks. To improve computation time, we produce the corner pattern using classified and detected corner points. After producing the corner patterns, it is estimated that mobile robot's global position by matching them. The estimated position is used as measurement model in the EKF. To evaluated proposed method, we preformed the experiments in the indoor environments. Experimental results of proposed method are shown to maintain an accuracy and decrease the computation time.

This paper presents a Proportional Integral Derivative controller based on Differential Voltage Current Conveyor Transconductance Amplifier as an active element. In the proposed circuit, the PID parameters namely, Proportional gain constant, Integral time constant and Derivative time constant can be tuned electronically by varying the bias current of the circuit. All the passive elements used are grounded, making it suitable for on-chip implementation. This circuit can be utilized to realize PI and PD controller.

This paper is concerned with speech enhancement using Phase-Error based Filters (PEF) and Excitation Source (ES) information in car environments. For this purpose, we firstly use ES information to determine the time-delay from speech signals obtained by two microphones for sound source localization. Then, the phase-error based filters are performed by prior knowledge regarding the time delay obtained by ES information and the phases of the signals recorded by the microphones. The experimental results showed the effectiveness of the presented method for speech enhancement.

The demand for electricity is increasing day by day in all sectors so that to reduce the electricity cost and to save electricity, industrial and building customers require smarter energy management systems. So first need to understand their electrical energy consumption, monitor the real time data and historical data of electricity. Also analyze all data of electricity for better energy management so as to reduce the electricity cost and plan according to it to reduce the consumption. ISO-50001 is a global standard, which describes the energy management system and it is applied to all industries. To address this issue an energy monitoring solution is developed which gathers the electricity data of all sectors at one station. Also provides graphical user interface, generates online and historical trend to analyze the load and consumption information. The electricity data is saved in .csv file format so that we can trace the electricity information of any day and instance. Password protection is provided to give the limited access as per role of the user. So that to achieve demand of small scale industry and building customers.

The current state-of-art trajectory tracking control for four wheel differential driven vehicle is found to be unreliable in certain cases. The vehicle motion needs to be controlled using optimization algorithms in order to follow the desired trajectory satisfactorily. Sliding mode controller (SMC) is employed for such non-linear systems to make trajectory tracking robust taking into account all surrounding uncertainties. The algorithm obtains an intermediate sliding surface for the vehicle such that the error between actual and desired trajectory is minimum. In this paper, Genetic Algorithm has been used to tune SMC gain parameters. The mathematical model of the vehicle has been developed in the paper for generating desired control actions. The conventional PID control is also applied separately for trajectory tracking by the vehicle. A comparative analysis between two controllers is presented in this paper. The results obtained show the tracking efficiency of SMC even in the presence of disturbances.

In this paper, we propose a new localization system using ceiling outlines. We acquire the entire ceiling image by using fisheye lens camera, and extract the lines by binarization and segmentation. The optical flow algorithm is then applied to identify the ceiling region from the segmented regions. Finally we obtain the position and orientation of the robot by the center position and momentum of ceiling region. Since we use the fully detected outlines, the accuracy and reliability of the localization system is improved. The experimental result are finally presented to show the effectiveness of the proposed method. Copyright © The Korean Institute of Electrical Engineers.
