In this paper a new approach for solving the H2 control problem using static state-feedback for LTI singular perturbation systems is proposed which achieves a minimum bound on the H2 performance level of closed-loop system. The proposed controller is given in terms of the solution of a set of matrix inequalities independent of singular parameter ∊. These inequalities are not in the form of linear...
The protection of busbar demands high integrity and high speed relaying scheme. This paper presents a new differential relaying scheme for the protection of busbar. The proposed scheme depends on the difference of the value of incoming and outgoing line currents of the respective phase at a particular bus. The proposed scheme has been tested extensively using the PSCAD/EMTDC software package with...
This paper presents a new classification scheme for power transformer which effectively discriminates between internal faults (phase to ground, phase to phase & phase to phase to ground) and non-internal faults (magnetising inrush, external fault & normal condition). The proposed scheme utilizes CT secondary current signals from both sides (LV and HV) of transformer windings as an input. Various...
Unmanned Aerial Vehicles (UAV) are an area of significant research activity these days in both academic and commercial circles. This paper presents a complete design of a Vertical Take-Off and Landing type unmanned aerial vehicle suitable for academic research purposes. The design encompasses both electrical and mechanical aspects. Particular details are provided for the material required for manufacturing...
The task of estimating the location of a mobile transceiver using the Received Signal Strength Indication (RSSI) values of radio transmissions is an inference problem. Contextual information, i.e., if the target is in a specific region, is sufficient for most applications. Therefore, instead of estimating position coordinates, we take a slightly different approach and look at localization as a classification...
The paper describes direct vector control with stator flux orientation for controlling the speed a PWM inverter induction motor drive system without speed sensor. Modeling and simulation results of the drive system are presented with some practical results. The proposed control method assures good dynamic response of the system.
Sea target detection is an important goal for military purposes and navigation. Environmental noise and sea clutter are two major problems in sea target detection. A new novel Neural Network in Kernel Space (NNKS) is presented for classification of the target and non-target in color images, and it is followed with a new kernel neuron sea target detection system (KNNS) which is efficient especially...
Looking at the works of Canadian poets bpNichol and Christian Bök examined are the applications of graph theory and combinatorics to 'pataphysical poems. A 'pataphysical poem is one which is seen as poetry which mocks science. However, these poems require knowledge of mathematics on the part of the poet. An analysis of bpNichol's Sixteen Lilypads uses elements of graph theory and provides a new reading...
This paper presents a novel modulated power filter compensator (MPFC) scheme for the smart grid stabilization and efficient utilization. The MPFC is controlled by a novel tri-loop dynamic error driven inter coupled modified PID controller. The Matlab digital simulation models of the proposed MPFC scheme has been fully validated for effective power quality (PQ) improvement, voltage stabilization, power...
In this paper a new gain stage for comparator-based switched-capacitor circuits (CBSC) is presented. In contrast with the conventional structure the proposed structure utilizes an extra comparator to make a variable comparator threshold, in order to attenuating the overshoot at the end of the coarse phase. To verify the idea, we designed a 2–1–1 cascaded MultiStage (MASH) ΔΣ modulator, based on the...
Optical networks have been widely adopted as the transport network in research industry for years. To better utilize the high speed benefit of optical transport networks, control framework has become the focus of research in recent years. This paper presented a control framework integrated with a set of algorithms, schemes and protocols. First, a two-level hierarchical routing strategy was introduced...
RFID technology has been widely used in logistic and authentication applications, but it still has many potential issues such as the risks of privacy and security. This paper presents a novel RFID security protocol based on the XTEA encryption. Analysis of the security and privacy of this novel protocol is performed using SystemC based modeling. Different attack models are implemented, and the results...
This paper examines the upcoming world of Wireless Services and Intelligent Vehicle Transportation System (IVTS). Recent advances in powerful and miniature computing, and transceiver technology, is enabling more technology to be placed inside a vehicle. The wireless sensors and transceivers onboard individual cars can communicate with other cars, or with the road. The information collected by individual...
Optimizing the use of copper especially in the distribution system not only reduces the cost but more importantly lowers the copper losses. This paper presents a unique innovative technique which reduces copper volume while enabling home automation. This model of smart home is designed to provide a base for Smart Grid's functions like demand side management, AMR, load shedding etc. The optimization...
