ROBOT DIRECTION CONTROL USING (RF) WITH VOICE FEEDBACK



Scope:
A robot is a mechanical or virtual artificial agent. In practice, it is usually an electro-mechanical system which, by its appearance or movements, conveys a sense that it has intent or agency of its own. The word robot can refer to both physical robots and virtual software agents, but the latter are usually referred to as Robots There is no consensus on which machines qualify as robot ....etc

MAGNETIC LEVITATION SYSTEM
plant consists of an electromagnet, an optic position sensor, a
ferromagnetic sphere and a power interface.
Due to the spherical shape the measurement is nonlinear and needs
to be electronically or digitally linearised.

Velocity estimation
For fast nonlinear and unstable dynamical systems, such as magnetic
levitation, high quality of control is essential.
The ball velocity measurement is a dicult task.
Measurements of position and current is used for the velocity
estimatio ....etc

Abstract

Here, the students learn how brushless DC motors have made personal electric vehicles (PEVs) possible, and calculate how much using a PEV instead of an automobile for some of their daily driving can impact their production of carbon dioxide, based on United States driving patterns. In the laboratory, students build a brushless DC motor using three different control methods, based on a reed switch, a Hall effect sensor, and optoelectronics, respectively. In the process, students learn about ....etc

Feedback Control Systems



Introduction
Your body is jammed full of feedback control systems. A few examples of things so controlled are: Blood pressure; blood volume; body temperature; circulating glucose levels (by insulin); blood partial pressures of carbon dioxide and oxygen (PCO2 , PO2 ); pH; hormone levels; thousands of proteins that keep cells alive and functioning. Without these control systems, life would not be possible. These are just a few example ....etc

Abstract
Developing effective mechanisms for feedback collection in learning environments is particularly important at the frontiers of new knowledge .Valuing and asking for feedback has recognized benefits for both staff and students. For Staff to provide information for course design to further develop teaching skills as well as to provide better service to the students. For Students to feel valued and 'listened' to have ownership in their own learning to develop reflective thinking to be better informed in selecting a course/module . The o ....etc

Abstract”
A major disadvantage of applying sliding mode control to dc/dc converters is that the steady-state switching frequency is affected by line and load variations. This is undesirable as it complicates the design of the input and output filters. To reduce switching frequency deviation in the events of line and load variations, an adaptive feedforward control scheme that varies the hysteresis band according to the change of line input voltage and an adaptive feedback control scheme that varies the control parameter (i.e., sliding c ....etc

Open loop control vs. closed loop (feedback) control



The next two figures present the structures of open loop and feedback control systems.
Figure 1 shows an open loop control system whose function is to cause the output y(t) to follow the
reference r(t).
Feedback control system design for zero steady state error
In general, to follow a reference R(s) with zero steady-state error, the path between the
reference and the system output should contain a term like R(s). For instance, to follow a ramp
(velocity ....etc

1. INTRODUCTION
We have developed Student Staff Feedback System to provide feedback in an easy and quick manner to the college principal and Hod’s. So we call it as Student Staff Feedback System which delivers via the student staff interface as online system which acting as a Service Provider
By using this technology we can make fast feedback about the staff by students on time to head of departments as they referred in online system.
This project has four kinds of users Student, Staff, Hod’s, an ....etc
