Stability derivatives — are a means of linearising the equations of motion of an atmospheric flight vehicle so that conventional control engineering methods may be applied to assess their stability.The dynamics of atmospheric flight vehicles is potentially very… … Wikipedia
Yaw axis — is a vertical axis through an aircraft, rocket, or similar body, about which the body yaws; it may be a body, wind, or stability axis. Also known as yawing axis. [cite web|url=http://www.websters online… … Wikipedia
Nyquist stability criterion — The Nyquist plot for . When designing a feedback control system, it is generally necessary to determine whether the closed loop system will be stable. An example of a destabilizing feedback control system would be a car steering system that… … Wikipedia
Electronic stability control — (ESC) is a computerized technology [1][2] that may potentially improve the safety of a vehicle s stability by detecting and minimizing skids.[3] When ESC detects loss of steering control, it automatically applies the brakes to help steer the… … Wikipedia
BIBO stability — Bibo redirects here. For the Egyptian football player nicknamed Bibo, see Mahmoud El Khateeb. In electrical engineering, specifically signal processing and control theory, BIBO stability is a form of stability for signals and systems.BIBO stands… … Wikipedia
Directional stability — is stability of a moving body or vehicle about an axis which is perpendicular to its direction of motion. Stability of a vehicle concerns itself with the tendency of a vehicle to return to its original direction in relation to the oncoming medium … Wikipedia
Relaxed stability — In aviation, relaxed stability is the tendency of an aircraft to change its attitude and angle of bank on its own accord. An aircraft with relaxed stability will oscillate in simple harmonic motion around a particular attitude at an increasing… … Wikipedia
longitudinal stability — The stability of an airplane about the lateral (pitching) axis. An airplane is stable if, when its angle of attack is temporarily increased, forces act in such a way as to push the nose down and thus decrease the angle of attack. The main factors … Aviation dictionary
directional stability — The stability that concerns yawing about the normal, or vertical, axis. An aircraft is directionally stable if when it is temporarily deflected from its course, it tends to return to the original course without any correction applied by the pilot … Aviation dictionary
Marginal stability — In the theory of dynamical systems, and control theory, a continuous linear time invariant system is marginally stable if and only if the real part of every eigenvalue (or pole) in the system s transfer function is non positive, and all… … Wikipedia
lateral stability — The stability of an airplane that occurs about the longitudinal axis. An aircraft is laterally stable in that when a slight roll takes place, the forces acting on the airplane tend to restore it to even keel (i.e., level flight) without any… … Aviation dictionary
