Just make a moment to listen to your body. What do I mean by listen to your body ? We think of bodies as concrete physical structure. However, from the understanding of both the most highly developed cultures throughout history and the latest discoveries of the quantum physics, we realize that at the basis of everything in our universe, including our bodies there is nothing other than energy or sound. At their deepest level, our bodies are nothing other than intelligence. This intelligence manifests into different sounds, or energetic vibrations that become the subatomic particles, atoms, cells, tissues, organs, and organ system of our physical bodies. It is said that if we able to raise our level of consciousness to that of an enlightened sage, we can literally here the sounds at the basic of our own mind and bodies.

He walked several miles that day but could not get anything to eat or drink except some dry bread and some water, which he got from cottagers and farmers. As night fell, he slept under a haystack lying in a meadow. He felt frightened at first, for the wind blew awfully over the empty fields. He felt cold and hungry, and was feeling more lonely than he had ever felt before. He, however , soon fell asleep, being much tired with his long walk, When he got up next day. he was feeling terribly hungry so he purchased a loaf of bread with a few coins that he had.

Regardless of how the state's feedback control law is designed, it is almost always necessary to implement it, using estimates of the state obtained from an observer. Hence, it is necessary to insure so that the desirable properties of the state feedback design do not vanish when the state estimate are used. It is proven in linear system theory courses that the command response is unaffected by the presence of the observer. However, the response to initial conditions will affect the system output. It is suggested that the observed poles should be made faster than the state feedback poles by an amount that depends upon the level of measurement noise. These conclusions are generally based upon transient time response properties of the system, and not on feedback properties such as robustness margins, We now present a procedure for tuning an observer so that, under appropriate conditions, the feedback properties of a state feedback design are recovered.
