An up-to-date survey of the theory of port-Hamiltonian systems is given, emphasizing novel
developments and relationships with other formalisms. Port-Hamiltonian systems theory …

This paper presents a survey of the most significant results on robust control theory. In
particular, we study the modeling of uncertain systems, robust stability analysis for systems …

Manufacturing equipment and scientific instruments, including wafer scanners, printers,
microscopes, and medical imaging scanners, require accurate and fast motions. An increase …

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 …

In tracking applications, following the signal detection process that yields measurements,
there is a procedure that selects the measurement (s) to be incorporated into the state …

In contrast to the well-developed gain analysis for multi-input-multi-output (MIMO) linear time-
invariant (LTI) systems, the research on the phase analysis does not share the same status …

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 …

The movement of cooperative robots in a densely cluttered environment may be impossible
if the formation type is invariant. Hence, we investigate a novel method of switching time …

In this paper, we define the phase response for a class of multi-input multi-output (MIMO)
linear time-invariant (LTI) systems whose frequency responses are (semi-) sectorial at all …

In this article, we define the notion of stable input–output negative imaginary (IONI) systems.
This new class captures and unifies all the existing stable subclasses of negative imaginary …
