H∞ Design of the F/A-18A Automatic Carrier Landing System

In this chapter a design of the F/A-18A Automatic Carrier Landing System is accomplished using finite horizon H ∞ techniques. If the final time is sufficiently large, the dynamic Riccati equations involved in the design of the suboptimal output feedback controller give rise to constant solutions. Only longitudinal equations of motion are considered, and thrust is incorporated as a control variable. The object of the design is to maintain a constant flight path angle under worst-case conditions of vertical gust and sensor noise during carrier landing. The design yields satisfactory response for vertical rate command as well.
