Force-Canceling Mixer Algorithm for Vehicles with Fully-Articulated Radially Symmetric Thruster Arrays
… of excessive thruster forces to maintain precise control despite little or no throttle authority. After defining the physical attributes of the new vehicle, a flight control mixer algorithm is defined and presented. This mixer is an input/output abstraction that grants a flight control system (or …

A comparison of the use of classical and modern control design techniques for improving the lateral-directional powered approach flying qualities of the F-14 aircraft
Due to the limitations of its analog flight control system, the F-14 aircraft exhibited several major flying qualities deficiencies. To correct these deficiencies, the Department of the Navy instigated a program to replace the analog system with digital flight control computers incorporating …
