Structured Linear Quadratic Regulator Design
2023 27th International Conference on System Theory, Control and Computing (ICSTCC), 2023 In this paper, we study linear quadratic regulator (LQR) design subject to linear equality constraints in the controller parameters. Necessary solvability conditions are provided, and a method for choosing the weighting matrices in the quadratic ...

On adaptive Linear–Quadratic regulators [PDF]
Automatica, 2020 Performance of adaptive control policies is assessed through the regret with respect to the optimal regulator, which reflects the increase in the operating cost due to uncertainty about the dynamics parameters. However, available results in the literature do not provide a quantitative characterization of the effect of the unknown parameters on the ...

Constrained linear quadratic regulation [PDF]
IEEE Transactions on Automatic Control, 1998 Summary: This paper is a contribution to the theory of the infinite-horizon Linear Quadratic Regulator (LQR) problem subject to inequality constraints on the inputs and states, extending an approach first proposed by Sznaier and Damborg. A solution algorithm is presented, which requires solving a finite number of finite-dimensional positive definite ...

On the Sample Complexity of the Linear Quadratic Regulator [PDF]
Foundations of Computational Mathematics, 2019 This paper addresses the optimal control problem known as the Linear Quadratic Regulator in the case when the dynamics are unknown. We propose a multi-stage procedure, called Coarse-ID control, that estimates a model from a few experimental trials, estimates the error in that model with respect to the truth, and then designs a controller using both the

Risk-Constrained Linear-Quadratic Regulators [PDF]
2020 59th IEEE Conference on Decision and Control (CDC), 2020 We propose a new risk-constrained reformulation of the standard Linear Quadratic Regulator (LQR) problem. Our framework is motivated by the fact that the classical (risk-neutral) LQR controller, although optimal in expectation, might be ineffective under relatively infrequent, yet statistically significant (risky) events.

Linear Quadratic Regulator and Fuzzy Control for Grid-Connected Photovoltaic Systems
Energies, 2022 This work presents a control scheme to control a grid-connected single-phase photovoltaic (PV) system. The considered system has four 250 W solar panels, a non-inverting buck-boost DC-DC converter, and a DC-AC inverter with an inductor-capacitor-inductor

A Hybrid Linear Quadratic Regulator Controller for Unmanned Free-Swimming Submersible
Applied Sciences, 2021 An unmanned free-swimming submersible (UFSS) is designed to perform certain tasks in water without interposing humans. The vehicle’s control is achieved by integrating mathematical (analog) and non-mathematical (embedded) controllers.
