Negative imaginary (NI) systems play an important role in the robust control of highly
resonant flexible structures. In this paper, a generalized NI system framework is presented. A …

This paper extends the robust feedback stability theorem of negative imaginary systems by
removing restrictive assumptions on the instantaneous gains of the systems that were …

This paper deals with the notion of output strictly negative-imaginary systems. A definition is
given for the class of output strictly negative-imaginary systems and a lemma is proposed to …

Negative-imaginary systems have important engineering applications, for example, in lightly
damped flexible structures with collocated position sensors and force actuators. This paper …

This brief addresses the vibration control of a marine riser-vessel system influenced by
extraneous disturbances and input backlash. By resolving the backlash nonlinearity as an …

The negative imaginary (NI) property is exhibited by many systems such as flexible
structures with force actuators and position sensors and can be used to prove the robust …

This note represents a first attempt to provide a definition and characterisation of negative
imaginary systems for not necessarily rational transfer functions via a sign condition …

This paper addresses the problem of dynamic output feedback controller synthesis in LMI
framework for LTI generalized plants with negative-imaginary uncertainties. The proposed …

A new form of nonlinear control scheme is presented in this brief where the concepts of
feedback linearization and adaptive control schemes are combined together to design an …

This paper utilizes a dissipative framework to construct a set of stabilizing controllers in
positive feedback for LTI negative imaginary (NI) systems with no pole at origin. The …
