Finding the Nearest Negative Imaginary System with Application to Near-Optimal Controller Design
Mohamed Mabrok
The negative imaginary (NI) systems theory has attracted interests due to the robustness properties of feedback interconnected NI systems. However, a full output optimal controller…
Lyapunov-based Stability of Feedback Interconnections of Negative Imaginary Systems
Ahmed G. Ghallab, Mohamed A. Mabrok, Ian R. Petersen
Feedback control systems using sensors and actuators such as piezoelectric sensors and actuators, micro-electro-mechanical systems (MEMS) sensors and opto-mechanical sensors, are a…
Ultra-wide frequency response measurement of an optical system with a DC photo-detector
Katanya B. Kuntz, Trevor A. Wheatley, Hongbin Song +4
Precise knowledge of an optical device's frequency response is crucial for it to be useful in most applications. Traditional methods for determining the frequency response of an op…
Sampling-based Learning Control for Quantum Systems with Uncertainties
Daoyi Dong, Mohamed A. Mabrok, Ian R. Petersen +3
Robust control design for quantum systems has been recognized as a key task in the development of practical quantum technology. In this paper, we present a systematic numerical met…
Generalizing Negative Imaginary Systems Theory to Include Free Body Dynamics: Control of Highly Resonant Structures with Free Body Motion
M. A. Mabrok, A. G. Kallapur, I. R. Petersen +1
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 New Stability Result for the Feedback Interconnection of Negative Imaginary Systems with a Pole at the Origin
Mohamed A. Mabrok, Abhijit G. Kallapur, Ian R. Petersen +1
This paper is concerned with stability conditions for the positive feedback interconnection of negative imaginary systems. A generalization of the negative imaginary lemma is deriv…
