Optimal Trajectory Tracking using an Output Feedback Preview Controller

This paper investigates the use of preview control for optimal trajectory tracking for air-to-surface missiles. An off-line reference trajectory is obtained by solving a trajectory optimisation problem that incorporates the mission constraints. A trajectory following guidance scheme using a preview controller is used to generate the on-line control. An example of a terminal guidance trajectory with a bunt (climb and dive) manoeuvre and a look angle constraint is presented to demonstrate the method.
