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 criterion provides a means for determining stability

Circulatory System The human body is made up of many different systems that perform our basic life functions. One such system is the circulatory system. This system transports oxygen and nutrients to organs and tissues within the body and carries away waste products. In performing these functions the circulatory system is associated with other systems in the body. The circulatory system is made up of the heart‚ blood and blood vessels. The heart is the main component of the circulatory system. It

P1 – State three purposes of pneumatic supply system for a typical piston engine powered light aircraft‚ and give the functions of the piston engine air compressor and receiver‚ within the system. An aircraft powered by a piston engine usually tends to have a pneumatic air supply system. This allows the function of different systems on the aircraft that are essential to the flight of the aircraft. In a newer system the supply system will provide a vacuum of air for the gyro’s‚ so that the de icing
