S. Askarpour et Tj. Owens, INTEGRATED APPROACH TO EIGENSTRUCTURE ASSIGNMENT BY OUTPUT-FEEDBACK -THE CASE OF MULTIPLE-EIGENVALUES, IEE proceedings. Control theory and applications, 145(3), 1998, pp. 265-268
An algorithm for eigenstructure assignment by output feedback, that in
tegrates subspace and parametric approaches to eigenstructure assignme
nt is extended to the general case of multiple eigenvalues. The extend
ed algorithm is less restrictive than another comparable algorithm. Th
e approach taken enables a gain index for moderating the gain of the r
esulting controller to be provided.
