Eigenstructure control involves modification of both the eigenvalues and eigenvectors of a system using feedback. Based on this key concept, algorithms are derived for the design of control systems using controller structures such as state feedback, output feedback, observer-based dynamic feedback, implicit and explicit modelfollowing, etc.

Sep 17, · From Summary: "Flight tests of a PH airplane with two different vertical-tail assemblies were made to determine lateral and directional stability and control characteristics. The airplane had satisfactory directional stability in the landing, approach, and wave-off conditions with either tail.
In the power-on clean and glide conditions, however, the airplane had weak directional stability Author: Christopher C. Kraft, J. Reeder. Lateral-Directional Dynamics * As we shall see, throttle also has effects on the At low AoA some stability derivatives depend on alfa, and at high angles of For each aircraft there is a mapping between trim states and trim control inputs.
