Abstract: A novel application of neural network approach to classify the fault types and to identify the faulty lines in a non radial power system network is demonstrated in this paper. EMTP software has been used to simulate the transmission line model. The simulation is followed by analysis of the current waveforms using wavelet transform in the MATLAB environment. The entropy values of the current signal obtained from wavelet transform have been fed into the neural network for automatic fault type classification and faulty line identification. It has been found that only three level of decomposition of the current signal is sufficient for analysis of faults. The adaptive discrimination scheme is tested under different types of faults, such as single line to ground faults, line-to-line faults, double line to ground faults and three phase symmetrical faults for different varying fault locations and fault resistances, on a given power system model. Results of performance studies show that the proposed scheme for fault diagnosis is able to classify all the faults and to identify the exact faulty lines on the non radial power system network rapidly and correctly.

Abstract: In orthopedic surgical simulators PMDC motors are used. A closed loop chopper controlled
scheme employing PID controller is attempted in this paper, which employs two power electronic switches one
for ON/OFF control and the other for speed control. The ON/OFF Control loop uses a hysteresis controller and
a PID controller is used for effective speed control of the motor. The closed loop system is simulated using
Matlab/Simulink. The responses of both the loops were analysed. The simulation results infer that this scheme
can give efficient control of the motor.

Abstract: This paper presents navigation system for an omni-directional AGV (automatic guided vehicle) with Mecanum wheels. The Mecanum wheel, one design for the wheel which can move in any direction, is a conventional wheel with a series of rollers attached to its circumference. The localization techniques for the general mobile robot use basically encoder. Otherwise, they use gyro and electronic compass with encoder. However, it is difficult to use the encoder because in the Mecanum wheel the slip occurs frequently by the rollers attached to conventional wheel's circumference. Hence, we propose the localization of the omni-directional AGV with the Mecanum wheel. The proposed localization uses encoder, gyro, and accelerometer. In this paper, we ourselves designed and made the AGV with the Mecanum wheels for experiment. And we analyzed the accuracy of the localization when the AGV moves sideways a 20m distance at about 20cm/s and 38cm/s, respectively. In experimental result, we verified that the accuracies of the proposed localization are 27.4944mm and 29.2521mm respectively.

Abstract: Control methods based on selective harmonic elimination pulse-width modulation (SHE-PWM) techniques offer the lowest possible number of switching transitions. This feature also results in the lowest possible level of converter switching losses. For this reason, they are very attractive techniques for the voltage-source-converter-(VSC) based high-voltage dc (HVDC) power transmission systems. The paper discusses optimized modulation patterns which offer controlled harmonic immunity between the ac and dc side. The application focuses on the conventional two-level converter when its dc-link voltage contains a mix of low-frequency harmonic components. Simulation and experimental results are presented to confirm the validity of the proposed switching patterns.
