DEVELOPMENT OF A DIGITAL GUIDANCE AND CONTROL LAW FOR STEEP APPROACH AUTOMATIC LANDINGS USING MODERN CONTROL TECHNIQUES

The development of a digital automatic control law for a small jet transport to perform a steep final approach in automatic landings is reported, along with the development of a steady-state Kalman filter used to provide smooth estimates to the control law. The control law performs the functions of localizer and glides capture, localizer and glideslope track, decrab, and place. The control law uses the microwave landing system position data, and aircraft body-mounted acceleraters, attitude and attitude rate information. The results obtained from a digital simulation of the aircraft dynamics, wind conditions, and sensor noises using the control law and filter developed are described.
