This paper proposes a consensus-based formation tracking scheme for multi-robot systems
utilizing the Negative Imaginary (NI) theory. The proposed scheme applies to a class of …

Cooperative control of networked unmanned aerial vehicles (UAVs) has received significant
research interest over the last decade due to its potential applications in military security and …

In this paper, we present necessary and sufficient conditions under which a linear time-
invariant (LTI) system is state feedback equivalent to a negative imaginary (NI) system. More …

This paper studies negative imaginariness and the static output feedback H∞ control
synthesis of descriptor systems based on the state–space symmetric model. First, under the …

This brief addresses the frequency-domain dissipativity problem of a broader class of Output
Negative Imaginary systems, termed as the time-domain ONI (or TDONI) systems, which …

Converse negative imaginary theorems for linear time-invariant systems are derived. In
particular, we provide necessary and sufficient conditions for a feedback system to be …

This paper develops a cooperative controller for a fleet of multi-tilt tricopter drones modelled
as Negative Imaginary (NI) systems via closed-loop linearisation exploiting Sliding-Mode …

In this study, we extend the theory of negative imaginary (NI) systems to a nonlinear
framework using a frequency-domain approach. The extended notion is completely …

This letter extends the class of systems to which negative imaginary (NI) stability result can
be (directly) applied. The existing closed-loop stability results for NI interconnections require …

This letter introduces the notion of linear Discrete-time Output Negative Imaginary (D-ONI)
systems. The D-ONI class is defined in the z-domain and it includes the systems having …
