ON NONLINEAR INNER SYSTEMS AND CONNECTIONS WITH CONTROL THEORY

open access: bronzeIFAC Proceedings Volumes, 2002
This paper extends some results involving linear inner systems to the nonlinear case. In thsi regard, the arithmetic of nonlinear inner systems is developed further and some new connections with nonlinear spectral and all-pass factorization and control theory are discussed.

Differential Systems and Nonlinear Control Theory

open access: bronzeIFAC Proceedings Volumes, 1995
Abstract Techniques from exterior differential systems provide a powerful geometric tool for the study of nonlinear systems. This paper presents a sketch of the relevant ideas and indicates both the ways in which they have already made an impact in control as well as some areas of future application.

THE GAP BETWEEN NONLINEAR CONTROL THEORIES AND APPLICATIONS IN POWER SYSTEMS

open access: bronzeIFAC Proceedings Volumes, 2007
Abstract The employment of nonlinear control theories in power system have brought along fruitful results to enhance transient stability. However, from the viewpoint of engineering, it is still a long distance between theoretical analysis and practical implementation.
