FOUR-DIMENSIONAL GUIDANCE PROBLEM WITH CONTROL DELAYS

This paper presents a mathematical model and investigates a computer-oriented algorithm to synthesize a three-dimensional flight th to guide an aircraft in a given time, T, from a given initial position, altitude, velocity, and heading to a prescribed final position, altitude, velocity, and heading subject to the constraints on velocity, acceleration, and pitch and bank angles of the aircraft. Such a precise time-position control problem, referred to as a four-dimensional (4-D) guidance problem in the literature, has been proposed as an advanced ATC technique. When applied to terminal guidance problems, the final position would be the Instrument Landing System (ILS) gate coordinates, final heading would be parallel to the runway, and terminal time, T, would be the assigned landing time slot.
