poised to become a figure-of-merit amongst the competing distribution utilities. Improvement of power quality has a positive impact on sustained profitability of the distribution utility on the one hand and customer satisfaction on the other. Electrical power is perhaps the most essential raw material used by commerce and industry today. It is an unusual commodity because it is required as a continuous flow- it cannot be conveniently stored in quantity - and it cannot be subject to quality assurance

CHAPTER 1 INTRODUCTION Now-a-days every institution needs automation. As a part of college automation‚ we have decided to do a project “voice interactive system for college automation”. Our project allows the user to know the student’s attendance and marks quickly through the telephone line without the intention of the college authority. In the hardware side embedded system has been used. The microcontroller controls the whole

INTRODUCTION Open- and closed-loop transfer functions have certain basic characteristics that permit transient and steady-state analyses of the feedback-controlled system. Five factors of prime importance in feedback-control systems are stability‚ the existence and magnitude of the steady-state error‚ controllability‚ observability‚ and parameter sensitivity. The stability characteristic of a linear time-invariant system is determined from the system’s characteristic equation. Routh’s stability
