Abstract:
The field oriented control emerged as an important approach for the control of AC machines, and continues to be explored and developed in the literature. The estimation of the rotor flux from the measurable variables was the only method used to implement the vector control of the induction machine. To replace the estimator based on the mathematical model of the system, which can lead to unintended errors due to uncertainties on the model and on the measures we use an appropriate observer.

Feedback linearization method for improvement of power systems transient stability
MINI PROJECT

ABSTRACT
Feedback linearization is a common approach used in controlling nonlinear systems. The approach involves coming up with a transformation of the nonlinear system into an equivalent linear system through a change of variables and a suitable control input. It is done by algebraically transforming non-linear system dynamics into a linear one so that linear control techniques can be applied. The canonical form and the general form of ....etc

ADAPTIVE AND NON-LINEAR EXCITATION CONTROL OF SYNCHRONOUS GENERATOR S STABILITY THROUGH NEURAL NETWORK

ABSTRACT
Adaptive and non linear Excitation control of synchronous generator s stability through Neural Network Control equipment of synchronous generators such as automatic voltage regulators, speed governors and power system stabilizers have been developed to maintain stability and to improve damping of the power systems. When an operating condition changes greatly, however, such controllers may become less effective bec ....etc

The electromagnetic devices extract a magnetising current from the source a.c, to establish the workflow. This magnetising current delays the applied voltage by almost 900.

A synchronous motor is a dual excitation machine, its armature winding is energised from a source a.c and its field winding from the d.c. When the synchronous motor is running at constant applied voltage, the resulting air gap flow required by the applied voltage remains constant. This resulting air gap flow is set by both a.c in the armature winding and d.c in the field ....etc

EXAMPLES ON LINEARIZATION



Consider the electromagnetic suspension system shown in the figure. An electromagnet is
located at the upper part of the experimental system. Utilizing the electromagnetic force f,
we desire to suspend the iron ball. Note that this simple electromagnetic suspension
system is essentially unworkable. Hence feedback control is indispensable. As a gap
sensor, a standard induction probe of eddy current type is placed below the ball.

Abstract
In this paper, new descriptor observer design approaches are presented for multivariable systems with measurement noises. If the system matrix is stable, the proposed modified proportional and derivative observer technique allows us not only to decouple the measurement noise in any forms completely, but also obtain accurate estimations of both system states and measurement noises. If the system is detectable and the noise is bounded, it has been shown that two design parameters can provide more degrees of freedom. In this context, th ....etc

SPEED SENSORLESS SEPARATELY EXCITED DC MOTOR DRIVE WITH AN ADAPTIVE OBSERVER


ABSTRACT
This project deals with a speed sensorless separately excited dc motor drive which uses the adaptive observer to estimate the rotor speed. The stability analysis of speed estimation is carried out. The modified feed forward control is integrated with the adaptive observer to simplify the implementation. The design guideline for feedback gain and the speed controller are also given to assure system stability for the entire operat ....etc

Abstract

A robust/adaptive stochastic observer is presented for stochastic nonlinear dynamics having excessive uncertainties. It was shown through a new theorem that the proposed nonlinear robust sliding mode observer has very accurate state estimate error characteristic. The observer uses the sliding mode technique for the robustness and a deterministic adaptive law to guarantees a globally asymptotically convergence observation error. Finally, an example is given to illustrate t ....etc
