Eigenspace techniques allow the control system designer to use feedback to place eigenvalues and shape eigenvectors so as to modify closed-loop dynamic response characteristics to achieve performance objectives. If performance specifications are given or can be interpreted in terms of designed closed-loop eigenvalues and/or eigenvectors, eigenspace design provides a method by which the feedback control gains required to produce the desired eigenstructure (if obtainable) can be calculated directly. If performance specifications cannot be stated in terms of rigid body eigenvalues and eigenvectors, for example, specifications on rms responses to gust inputs or stability margins, it may be necessary to iterate eigenvalues and/or eigenvectors until performance specifications are satisfied. The theory of eigenspace design is reviewed, extended and applied to several aircraft control problems.
