description abstract | This paper addresses the issue of determining the most desirable “nominal closedloop matrix†structure in linear state space systems, from stability robustness point of view, by combining the concepts of “quantitative robustness†and “qualitative robustness.†The qualitative robustness measure is based on the nature of interactions and interconnections of the system. The quantitative robustness is based on the nature of eigenvalue/eigenvector structure of the system. This type of analysis from both viewpoints sheds considerable insight on the desirable nominal system in engineering applications. Using these concepts, it is shown that three classes of quantitative matrices labeled “target sign stable (TSS) matrices,†“target pseudosymmetric (TPS) matrices,†and finally “quantitative ecological stable (QES) matrices†have features which qualify them as the most desirable nominal closedloop system matrices. In this paper, we elaborate on the special features of these sets of matrices and justify why these classes of matrices are well suited to be the most desirable nominal closedloop matrices in the linear state space framework. Establishment of this most desirable nominal closedloop system matrix structure paves the way for designing controllers which qualify as robust controllers for linear systems with real parameter uncertainty. The proposed concepts are illustrated with many useful examples. | |
