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 …

The invention of the nanotechnology adds a new branch to investigate and control the
physical properties of matters at atomic level. The aim of this technology is to image the …

This paper introduces the class of Time-Domain Input–Output Negative Imaginary (TD-IONI)
systems. The new TD-IONI definition unifies the class of the existing Negative Imaginary (NI) …

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 …

This paper proposes a new dam** control approach with positive acceleration, velocity
and position feedback (PAVPF) scheme for piezo-actuated nanopositioning stages to …

The paper describes an XY nanopositioning stage constructed from flexures and actuators
machined into a single sheet of piezoelectric material. Ultrasonic machining is used to …

This paper presents the design of a high-performance second-order controller for voltage
control of a single-and three-phase islanded microgrid under different loads and fault …

This paper presents a new dam** control scheme for piezo-actuated nanopositioning
stages with recursive delayed position feedback (RDPF). The RDPF is proposed to …

This paper generalises the notion of output strictly negative imaginary systems and provides
a complete characterisation both in frequency domain and time domain. The paper also …

In this work, a data-driven based cross-coupling compensation (DD-CCC) method is
proposed to suppress the cross-coupling effect of the scanner in atomic force microscopy …
