In this paper, the consensus problem of a continuous-time uncertain multi-agent system
(MAS) with time-varying interval uncertainties in the system matrix and unknown initial states …

This letter introduces the notion of linear timevarying (LTV) negative imaginary systems. LTV
negative imaginary systems are defined using a time-domain dissipative supply rate w (u, ẏ) …

This paper proposes a robust formation control scheme for networked multi-tilt tricopter
UAVs utilizing the Negative Imaginary (NI) and Positive Real (PR) theory. A Sliding Mode …

In this article, the state-space symmetric systems with symmetrical interval uncertainty that
have positive real and negative imaginary properties are studied. First, a necessary and …

Abstract In the Single-Input-Single-Output (SISO) setting, Negative Imaginary (NI) systems
refer to systems with negative frequency response for all positive frequencies. The NI theory …
