SPEED CONTROL OF DC SHUNT MOTOR USING MICRO CONTROL BASE


INTRODUCTION:-
DC motor speed controllers are very useful for controlling the motion of robotic and industrial automation systems. The controller presented here uses the PWM technique. The PMW wave for speed control is generated using Atmel AT89C51 microcontroller. To control the speed of the DC motor, you need a variable power supply. When the DC motor is switched on, i ....etc

JOURNAL OF ADDICTIVE DISORDERS

SUMMARY
An examination of whether the Internet is a “pathological agent” and should be included as a disorder separate from other psychiatric diagnoses, including discussion of Internet overuse, the distinction between addictions, compulsions and impulses, technology as a non-chemical addiction, symptoms suggesting addiction potential of the Internet, the prevalence and demographic profile of addicts, uniqueness of the etiology, contrary theories, and placement of the pathological Internet ....etc

The Impact of Control Delay upon the Performance of a DC-Motor Control: Comparison of a Centralized vs. a Network-Based Approach
Abstract
An important aspect when dealing with computer control systems is the impact of control delay upon the performance of the controlled item. Such control delay may be a consequence of the computer controlled implementation or, for the case of a network based control system, can be the consequence of the use of a communication network to interconnect sensors and actuators with the controller. Ba ....etc

Today, home appliance applications require more and more features such as motor speed adaptations to multipurpose accessories, user-friendly interfaces, and security features. Such new requirements can be achieved through a low-end microcontroller-based electronic control using the fuzzy logic approach. Now a days, most of fuzzy logic-based controls are only limited to a complicated ranking management of user interfaces, sensors, and actuators, corresponding to slow software speed operation. This paper proposes a totally different use of fuzzy ....etc

SPEED CONTROL OF AN INDUCTION MOTOR USING INDIRECT VECTOR CONTROL
ABSTRACT
Over the past two decades technological advances in power electronics and an increasing demand for high performance industrial machinery have contributed to rapid developments in digital motor control. This field of study has numerous applications in the areas of manufacturing, mining and transportation but sometime it is difficult to determine which technique is best suited to a particular application.
Induction motor is used as a variable speed drive in many indus ....etc

Abstract. In this paper, we present some of our current studies on how human brain structures are influenced by cognitive disorders occurred from various neurological and psychiatric diseases based on magnetic resonance imaging (MRI). We first give a brief introduction about computational neuroanatomy, which is the basis of these studies. In Section 2, several novel methods on segmentations of brain tissue and anatomical substructures were presented. Section 3 presented some studies on brain image registration, which plays a core role i ....etc
