Optimal Firing Angle for d.c. Series Motor

Nabeel E. Adam

Volume 7, Issue 1 , June 2007, Page 31-40

Abstract
  Abstract: The input voltage to the direct current series motor is controlled by means of an optimal regulator, for changing the firing angle of the thyristors using pulse width modulation technique. An input output linearization technique is introduced to linearize the non–linear mathematical model ...  Read More ...

Abstract
  Abstract: Most of the positioning technologies for modern inertial navigation systems have been available for the last 25 years that has focused on development of the Strap-down Inertial Navigation Systems (SINS) because of its low cost. This paper presents an intelligent navigator to overcome the ...  Read More ...

PERFORMANCE EVALUATION OF ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING OVER FREQUENCY SELECTIVE RAYLEIGH FADING HF CHANNEL

Prof. Maher K. Al-Azawi; Mohanad E. Al-Madi

Volume 7, Issue 1 , June 2007, Page 50-61

Abstract
  Abstract : The effectiveness of Orthogonal Frequency Division Multiplexing (OFDM) with π//4-DQPSK modulation is investigated, for communication over HF channel. The Fast Fourier Transform (FFT) is used to satisfy the orthogonality between subcarriers and reduce the implementation complexity. The system ...  Read More ...

ROBUST SLIDING MODE CONTROL BASED ON IFOC INDUCTION MACHINE WITH SPEED ESTIMATOR

Dr. Noaman M. Noaman

Volume 7, Issue 1 , June 2007, Page 62-73

Abstract
  Abstract In this paper, an indirect field-oriented control (IFOC) induction machine drive with a conventional PI and sliding mode controllers is presented. The robustness of ac machine drive speed performance with these controllers is checked in terms of variation of machine parameters. The design ...  Read More ...

COLOR IMAGE IDENTIFICATION BASED ON 2-D POWER SPECTRUM BASED ON NEURAL NETWORK

M.Sc. Hassan J. Hassan

Volume 7, Issue 1 , June 2007, Page 74-86

Abstract
  Abstract: Image identification plays a great role in industrial, remote sensing, and military applications. It is concerned with the generation of a signature to the image. This work proposes a dynamic program (use Neural Network) to identify the color image depending on the distribution of the monochrome ...  Read More ...
