1. Fuzzy Logic Based Life Estimation of PWM Driven Induction Motors

T. G. Arora; M. V. Aware; D. R. Tutakne

Volume 1, Issue 2 , Summer and Autumn 2013, Pages 63-71

Abstract
  Pulse-width modulated (PWM) adjustable frequency drives (AFDs) are extensively used in industries for control of induction motors. It has led to significant advantages in terms of the performance, size, and efficiency but the output voltage waveform no longer remains sinusoidal. Hence, overshoots, high ...  Read More

2. A High Efficiency Low-Voltage Soft Switching DC–DC Converter for Portable Applications

P. Amiri; M. Sharafi

Volume 1, Issue 2 , Summer and Autumn 2013, Pages 73-81

Abstract
  This paper presents a novel control method to improve the efficiency of low-voltage DC-DC converters at light loads. Pulse Width Modulation (PWM) converters have poor efficiencies at light loads, while pulse frequency modulation (PFM) control is more efficient for the same cases. Switching losses constitute ...  Read More

S. Mohammadi; H. R. Mosaddegh; M. Yousefian

Volume 1, Issue 2 , Summer and Autumn 2013, Pages 83-88

Abstract
  This paper presents a novel control approach used in shunt active power filter based on variable structure control combined with Random PWM technique (RVSC) that provides robust, fast, and more favorable performance for active power filter. This control strategy is compared with two other strategies ...  Read More

4. An Improved Time-Reversal-Based Target Localization for Through-Wall Microwave Imaging

A. B. Gorji; B. Zakeri

Volume 1, Issue 2 , Summer and Autumn 2013, Pages 89-97

Abstract
  Recently, time reversal (TR) method, due to its high functionality in heterogeneous media has been widely employed in microwave imaging (MI) applications. One of the applications turning into a great interest is through-wall microwave imaging (TWMI). In this paper, TR method is applied to detect and ...  Read More

5. Automatic Sleep Stages Detection Based on EEG Signals Using Combination of Classifiers

R. Kianzad; H. Montazery Kordy

Volume 1, Issue 2 , Summer and Autumn 2013, Pages 99-105

Abstract
  Sleep stages classification is one of the most important methods for diagnosis in psychiatry and neurology. In this paper, a combination of three kinds of classifiers are proposed which classify the EEG signal into five sleep stages including Awake, N-REM (non-rapid eye movement) stage 1, N-REM stage ...  Read More

6. A Comparison of Different Control Design Methods for the Linearized CSTR Temperature Model

A. D. Shakib Joo

Volume 1, Issue 2 , Summer and Autumn 2013, Pages 107-114

Abstract
  Continuous Stirred Tank Reactor (CSTR) has particular importance in chemical industry. CSTR has usually a nonlinear behavior which makes it difficult to control. The reactor has two parameters: the concentration and temperature of mixture both of which are uncertain. This case of CSTR has large disturbance ...  Read More
