On the control of spin-boson systems [PDF]
2013 European Control Conference (ECC), 2013 In this paper, we study the so-called spin-boson system, namely, a two-level system in interaction with a distinguished mode of a quantized bosonic field. We give a brief description of the controlled Rabi and Jaynes–Cummings models and we discuss their appearance in the mathematics and physics literature.

Structural averaged controllability of linear ensemble systems [PDF]
arXiv, 2021 In the paper, we introduce and address the problem of structural averaged controllability for linear ensemble systems. We provide examples highlighting the differences between this problem and others. In particular, we show that structural averaged controllability is strictly weaker than structural controllability for single (or ensembles of) linear ...

On the controllability of a nonlinear control system
Computers & Mathematics with Applications, 1984 AbstractThis paper considers the problem of controllability of a class of nonlinear systems. Sufficient conditions are given for a nonlinear system to be locally controllable and globally completely controllable. In the case of a linear time-invariant system, these conditions are also necessary.

Sparse Linear Ensemble Systems and Structural Averaged Controllability: Single-input Case [PDF]
arXiv, 2023 We consider continuum ensembles of linear time-invariant control systems with single inputs. A sparsity pattern is said to be structurally averaged controllability if it admits an averaged controllable linear ensemble system. We provide a necessary and sufficient condition for a sparsity pattern to be structurally averaged controllable.

Design a Second Order Sliding Mode Controller for Electrical Servo Drive Systems [PDF]
Engineering and Technology Journal, 2019 The aim of this paper is to design and study a powerful second-order sliding mode controller for electrical servo drive systems. The suggested controller can successfully overcome the chattering problem that was usually facing such systems during ...

Encrypted Control System with Quantizer [PDF]
IET Control Theory & Applications, vol. 13, no. 1, pp. p. 146-151,
2019, 2018 This paper considers the design of encrypted control systems to secure data privacy when the control systems operate over a network. In particular, we propose to combine Paillier cryptosystem with a quantizer whose sensitivity changes with the evolution of the system.

Journal of Magnetic Resonance Open, 2022 In design of a chirp inversion pulse, we keep the sweep rate a≪ω12, where ω1 is the amplitude of the pulse. This is the adiabaticity condition for the inversion to work.

A Hybrid Algorithm Based Static Model Updating Method and Its Application to Spacecraft
Advances in Materials Science and Engineering, 2022 In some cases, the static model updating requires more precise results to satisfy the requirement of simulating the structural response. The corresponding optimization algorithm not only should have a stronger capability to find the global optimum, but ...
