This paper discusses artificial neural network (ANN) controlled superconducting magnetic energy storage (SMES) unit for improvement of transient stability of a power system under various system operating conditions and different fault conditions. The inputs to the ANN controller are the deviation in rotor angular velocity Δω of the machine connected to faulted-bus and the voltage deviation Δν of the...
Robot environment map is used for the path planning. Sonar Sensor measurement is converted to the probabilistic representation of the environment (occupancy grid). In this paper we used sonar sensor model to identify the different regions of the robot on the floor (cells). We used the grid mapping to describe the emptiness and occupancy and the unknown areas of the robot environment and the nearby...
OFDM digital communication system is highly frequency sensitive to carrier frequency offset between transmitter and receiver local oscillators, which disturbs orthogonality among carriers. Consequently, the performance of OFDM system is reduced greatly due to inter-carrier-interference (ICI). In this paper, we have presented a novel approach for the frequency offset estimation of the OFDM communication...
The objective of this paper is to provide improved real-time noise canceling performance while keeping the high quality of enhanced speech by using new robust adaptive beamformer. The proposed beamformer uses a new adaptive blocking matrix, which consists of linear prediction error filters (LPEFs). It also employ a multi-channel noise canceller with adaptive noise estimation filters (ANEFs) used for...
