Sparse control for continuous‐time systems

M Nagahara - International Journal of Robust and Nonlinear …, 2023 - Wiley Online Library
In this survey article, we give a comprehensive review of sparse control for continuous‐time
systems, called maximum hands‐off control. The maximum hands‐off control is the optimal …

[图书][B] Sparsity methods for systems and control

M Nagahara - 2020 - library.oapen.org
The method of sparsity has been attracting a lot of attention in the fields related not only to
signal processing, machine learning, and statistics, but also systems and control. The …

Discrete-time hands-off control by sparse optimization

M Nagahara, J Østergaard, DE Quevedo - EURASIP Journal on Advances …, 2016 - Springer
Maximum hands-off control is a control mechanism that maximizes the length of the time
duration on which the control is exactly zero. Such a control is important for energy-aware …

Discrete-valued control of linear time-invariant systems by sum-of-absolute-values optimization

T Ikeda, M Nagahara, S Ono - IEEE Transactions on Automatic …, 2016 - ieeexplore.ieee.org
In this paper, we propose a new design method of discrete-valued control for continuous-
time linear timeinvariant systems based on sum-of-absolute-values (SOAV) optimization. We …

A new zero-order algorithm to solve the maximum hands-off control

H Mai, Z Yin - IEEE Transactions on Automatic Control, 2023 - ieeexplore.ieee.org
A new zero-order algorithm to solve the maximum hands-off control is proposed. Maximum
hands-off control is discretized into a convex linear programming problem by zero-order …

Sparsity-constrained controllability maximization with application to time-varying control node selection

T Ikeda, K Kashima - IEEE Control Systems Letters, 2018 - ieeexplore.ieee.org
In this letter, we consider the maximization of a quantitative metric of controllability with a
constraint of L 0 norm of the control input. Since the optimization problem contains a …

CLOT norm minimization for continuous hands-off control

M Nagahara, D Chatterjee, N Challapalli… - Automatica, 2020 - Elsevier
In this paper, we propose optimal control that is both sparse and continuous, unlike
previously proposed alternatives to maximum hands-off control. The maximum hands-off …

Time-optimal hands-off control for linear time-invariant systems

T Ikeda, M Nagahara - Automatica, 2019 - Elsevier
In this article, we investigate theoretical properties of the time-optimal hands-off control for
linear time-invariant systems. The purpose of the control is to maximize the time duration on …

A survey on compressed sensing approach to systems and control

M Nagahara, Y Yamamoto - Mathematics of Control, Signals, and Systems, 2024 - Springer
In this survey paper, we review recent advances of compressed sensing applied to systems
and control. Compressed sensing has been actively researched in the field of signal …

Resource-aware time-optimal control with multiple sparsity measures

T Ikeda, M Nagahara - Automatica, 2022 - Elsevier
The paper proposes a novel time-optimal control that is also sparse in both time and space
domain to take account of resource constraints in networked control systems. The control …
