This paper presents a survey of some of the main results in the theory of negative imaginary
systems. The paper also presents some applications of negative imaginary systems theory …

In this paper, an H∞ negative imaginary static output feedback (SOF) controller is designed
for a low frequency (LF) networked control system (NCS) with time-delays. A difference …

This paper considers the problem of robust stabilization of linear time‐invariant systems with
respect to unmodelled dynamics and structure uncertainties. To that end, a methodology to …

This article focuses on negative imaginariness of commensurate fractional-order linear time-
invariant systems. Enlightened by the generalized Kalman–Yakubovic–Popov lemma …

This paper addresses the robust output consensus problem for multiple homogeneous
negative imaginary (NI) systems subject to L 2 external disturbances and model …

We report a procedure to design fixed-structure strictly negative imaginary (SNI) controllers
for collocated, highly resonant systems based on frequency response data. We formulate the …

This article investigates mathematical modelling and control of a nonlinear negative
imaginary system using an illustrative benchmark physical example of a quadrotor dynamic …

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 …

In this paper, a multivariable integral resonant controller is designed based on the measured
frequency response of a 2-DOF MEMS nanopositioner with collocated sensors and …

This paper studies some useful properties of lossless negative imaginary transfer matrices
for both continuous-time and discrete-time systems. Necessary and sufficient conditions are …
