Abstract :
A sufficient condition is obtained for the robust stability of a linear time-invariant (LTI) plant with simultaneous time-varying structured state space uncertainty and unmodeled dynamics. The time-domain analysis results of robust constant gain output feedback are explicitly in terms of the closed-loop eigenvalues and eigenvectors and are well suited to the design of robust eigenstructure assignment controllers
