Partial eigenstructure assignment approach for robust flight control

A partial pole/eigenstructure method was proposed for robust flight control. Eigenstructure specifications are only given for partial modes, to acquire more freedom for the feedback design than the ordinary eigenstructure assignment approach. It is stated that the partial pole placement gain parameterization via polynomial matrix approach plays an important role in the proposed technique. The effectiveness of the technique was demonstrated by developing a mode decoupling robust flight control design by the statefeedback. The statefeedback achieved quadratic stabilization and partial eigenstructure assignment.
