    An efficient electricity theft and fault detection scheme in distribution system
    (Science International, 2016) Muhammad Fahad Zia; Fahad Ali
    Currently the world is facing energy (electricity) crisis and it is becoming severe with the passage of time. Every country is striving to produce and save electricity. In developing countries, especially, a considerable amount of revenue is lost due to electricity pilferage and fault occurrence on the distribution system. Therefore, it is required to design a system that would be able to detect electricity theft as well as the faults on the distribution system. This paper presents an efficient and simple technique which operates efficaciously as an electricity theft detector and also serves the function of a protective relay. In this scheme, each customer is provided with smart meter and a main observer meter is connected to distribution transformer. Meters send the readings to the data acquisition center where the proposed algorithm is applied to detect theft or fault scenario. Electricity theft can be considerably reduced by using this proposed metering technique. This algorithm can also identify associated areas of electricity theft.

    GUI based fuzzy logic control system
    (Science International., 2016) Muhammad Tahir Mushtaq
    The work presented in this paper addresses a generalized graphic user interface(GUI) based Fuzzy Logic Control System(FLCS) to design, edit and execute control system. The proposed system is a user friendly and easy to implement. It helps the user to create a fuzzy logic system in simple steps, inserting the names and membership functions details of all inputs and outputs defining the rule base for FLCS. Detailed structure of the system and design of modules, fuzzifier, inference engine, rule base and defuzzifier were discussed. The results of proposed model were compared with the results of MATLAB Simulink. This research work proposed to develop a novel control system to create and succeed FLCS in few steps efficiently.

    Position Control of Switched Reluctance Motor Using Super Twisting Algorithm
    (Mathematical problems in Engineering, Hindawi, 2015) Shaukat Iqbal
    The inherent problem of chattering in traditional sliding mode control is harmful for practical application of control system. This paper pays a considerable attention to a chattering-free control method, that is, higher-order sliding mode (super twisting algorithm). The design of a position controller for switched reluctance motor is presented and its stability is assured using Lyapunov stability theorem. In order to highlight the advantages of higher-order sliding mode controller (HOSMC), a classical first-order sliding mode controller (FOSMC) is also applied to the same system and compared. The simulation results reflect the effectiveness of the proposed technique.
