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.

On Vehicle Stabilization Under Saturation Constraints by Linear Quadratic Regulator
JEMMME (Journal of Energy, Mechanical, Material, and Manufacturing Engineering), 2022 The stability of a four-wheel vehicle is an issue widely discussed. As an effort to reduce accidents involving four-wheel vehicles, many studies have been conducted to develop a vehicle stability control system.

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.

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

Multiscale differential Riccati equations for linear quadratic regulator problems [PDF]
, 2018 We consider approximations to the solutions of differential Riccati equations in the context of linear quadratic regulator problems, where the state equation is governed by a multiscale operator.

Time-changed linear quadratic regulators [PDF]
2013 European Control Conference (ECC), 2013 Many control methods implicitly depend on the assumption that time is accurately known. For example, the finite-horizon linear quadratic regulator is a linear policy with time-varying gains. Such policies may be infeasible for controllers without accurate clocks, such as the motor systems in humans and other animals, since gains would be applied at ...
