EIGENSTRUCTURE ASSIGNMENT BY DECENTRALIZED FEEDBACK-CONTROL

The problem of eigenstructure assignment (eigenvalue and eigenvector a ssignment) plays an important role in control theory and applications. In this note, we introduce a new approach to eigenstructure assignmen t using decentralized control. First, several analytical results are p resented to characterize the set of decentralized controllers which ac hieve desired eigenvalue assignment. Then, a method is proposed to sim ultaneously assign eigenvalues and eigenvectors of a linear system usi ng decentralized control. The method is applied to the control of a po wer system to illustrate its effectiveness.
