[Tex/LaTex] bibliography in alphabetical order

sorting

I am using bibliography in the text as bibitem and citing this in the text it is coming correctly. Later I need to have bibiliography in the alphabetical order. How do I do it. I checked already given answers. Still I have doubt. Please, give me a piece of code which clearly gives the answer. Please, see the LaTeX code below for main file as well as reference file egbib.bib

\section{Introduction}

All physical systems are nonlinear in nature. Nonlinear control design technique like backstepping considers the nonlinearity also during design. The 1991 Bode lecture at IEEE CDC, held by Kokotovic was devoted to backstepping and in 1992 kanellakopoulos presented a mathematical toolkit for design of backstepping control laws. During the following year text books by Kristic \cite{kristic} Freeman , Kokotovic and Sepulchre were published.

The discrete-time feedback control techniques such as feedback linearization, backstepping and state dependent riccati equation methods in \cite{ref2}\cite{ref3} and  missile autopilot design was also considered in \cite{ref2} .The application of discrete time backstepping  to  various systems is given in \cite{ref2}\cite{ref4}.

The backstepping control technique is found to have a lot of advantages compared to feedback linearization and gain scheduling. Backstepping does not require exact model for design \cite{ref3}\cite{ref5}.The backstepping technique can solve tracking and regulator problems. It can also provide dead beat control and exact tracking of any desired trajectory in finite time and exploits the flexibility offered by lower order and scalar systems. Backstepping technique takes advantage of useful nonlinearities which help in making the Lyapunov derivative negative definite \cite{kristic}.The discrete backstepping technique has been applied to roll control and sideslip angle control of a reusable launch vehicle. The system is discretized first and then the controller is developed step by step and has given very good tracking and stabilizing performance.

my requirement is all bibiliographic items should come in the text and it should be in alphabetical order.
thank you
geetha

Well, are you giving us a free hand by just demanding alphabetical sorting? ;-) You can use natbib, replace all \cite with \citet (or \citep if you like) and put this for example

\bibliographystyle{apa}
