Proceedings ArticleDOI
Nonlinear versus linear control in the absolute stabilizability of uncertain systems with structured uncertainty
Andrey V. Savkin,Ian R. Petersen +1 more
TL;DR: In this paper, the authors considered a stabilization problem for a class of uncertain linear systems containing structured uncertainty, where the uncertainties in the system are described by a certain integral quadratic constraint which allows for a rich class of uncertainties including nonlinear dynamic time-varying uncertainty.
Journal ArticleDOI
Identification of Non-Markovian Environments for Spin Chains
TL;DR: In this paper, a gradient algorithm is proposed to identify correlations in terms of the time-varying damping rate functions in a time-convolution-less master equation for spin chains.
Journal ArticleDOI
Robust manipulation of superconducting qubits in the presence of fluctuations
TL;DR: In this article, a sampling-based learning control (SLC) method is used to guide the design of control fields for manipulating superconducting quantum systems, and the results show that the "smart" fields learned using the SLC method can achieve robust manipulation of qubits, even in the presence of large fluctuations and inaccuracies.
Journal ArticleDOI
Weak robust controllability and observability of uncertain linear systems
Andrey V. Savkin,Ian R. Petersen +1 more
TL;DR: It is shown that the conditions of weak robust observability and full information weak robust controllability are necessary but not sufficient for partial information weak resilient controllable systems.
Journal ArticleDOI
Nonlinear versus linear control in the direct output feedback stabilization of linear systems
TL;DR: In this paper, the use of nonlinear direct output feedback in the control of linear time-invariant systems is investigated, and it is shown that any linear system which can be made quadratically stable using nonlinear feedback control can also be stabilized using linear feedback control.
