Fuzzy supervisory controller for improved voltage dynamics in power factor corrected converter
(2002)
This paper investigates the performance of a Fuzzy Supervisory Controller (FSC) in control of power converters. An FSC module is added to a conventional narrow bandwidth voltage regulator in a Power Factor Corrected (PFC) ...
A novel DC bus voltage sensorless PFC rectifier with improved voltage dynamics
(2002)
A novel DC bus voltage estimation algorithm with inherent cancellation of feedback voltage ripple is presented in this work. Design issues are discussed and simulation results are presented. Apart from reduction of output ...
A simple fast voltage controller for single-phase PFC converters
(2002)
In this work a simple and robust voltage controller is proposed to improve voltage dynamics in the power factor corrected (PFC) converters. The proposed controller eliminates twice the line frequency ripples from the voltage ...
Applications of artificial intelligence techniques for induction machine stator fault diagnostics: review
(2003)
The on-line fault diagnostics technology for induction machines is fast emerging for the detection of incipient faults as to avoid the unexpected failure. Approximately 30-40 % faults of induction machines are stator faults. ...
Performance analysis of adaptive fuzzy logic controller for switched reluctance motor drive system
(1998)
This paper presents the application of an adaptive fuzzy algorithm for the speed control of a switched reluctance motor (SRM). The SRM is a highly nonlinear control plant and operates in saturation to maximize the torque ...
Analysis of switched reluctance motor drive under fault conditions
(1998)
The paper presents a comprehensive analysis of a switched reluctance motor (SRM) drive system under different realistic fault conditions. A simple modeling and simulation technique is used to investigate the fault tolerant ...
A universal active power filter for single-phase reactive power and harmonic compensation
(1998)
In modern power distribution systems, the majority of loads draw reactive power and/or harmonic currents from the AC source along with main active power currents. These nonunity power factor linear and nonlinear loads cause ...
Power factor correction and load balancing in three-phase distribution systems
(1998)
This paper deals with the different methods for compensating unbalanced three phase loads. Compensation of grounded, ungrounded star connected and delta connected three phase unbalanced load has been carried out. Three ...
Comparison of PI, VSC and energy balance controller for single phase active filter control
(1998)
This paper presents a comparison among proportional-integral, variable structure voltage controller and energy balance controller for the control of single phase active filter. Proportional-integral (PI) and variable ...
An improved converter with power factor correction of 3-phase auxiliary loads
(1998)
This paper deals with the performance analysis of an improved converter which is capable of supplying reactive power of other 3-phase linear loads at the common point of connection to the AC mains. The converter with ...
