LQR and SMC stabilization of a new unmanned aerial vehicle [PDF]

, 2009
We present our ongoing work on the development of a new quadrotor aerial vehicle which has a tilt-wing mechanism. The vehicle is capable of take-off/landing in vertical flight mode (VTOL) and flying over long distances in horizontal flight mode.

The role of identification in data‐driven policy iteration: A system theoretic study

International Journal of Robust and Nonlinear Control, EarlyView.
Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

Regret-Optimal LQR Control

, 2021
We consider the infinite-horizon LQR control problem. Motivated by competitive analysis in online learning, as a criterion for controller design we introduce the dynamic regret, defined as the difference between the LQR cost of a causal controller (that has only access to past disturbances) and the LQR cost of the \emph{unique} clairvoyant one (that ...

Control System for the Navigation of the Agricultural Robots: A Review

Journal of Field Robotics, EarlyView.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

The LQR-Schrödinger Bridge

2025 IEEE 64th Conference on Decision and Control (CDC)
We consider the Schrödinger bridge problem in discrete time, where the pathwise cost is replaced by a sum of quadratic functions, taking the form of a linear quadratic regulator (LQR) cost. This cost comprises potential terms that act as attractors and kinetic terms that control the diffusion of the process. When the two boundary marginals are Gaussian,

Consent and Gender‐Based Violence: R v Hobday

The Modern Law Review, EarlyView.
This note analyses the Court of Appeal decision in R v Hobday in the context of the longstanding but controversial caselaw on the relevance of consent to offences of assault occasioning actual bodily harm (ABH) or above. It considers whether the vulnerabilities of victims of gender‐based violence are adequately recognised by the judiciary in an area ...

Policy Gradient for LQR with Domain Randomization

2025 IEEE 64th Conference on Decision and Control (CDC)
Domain randomization (DR) enables sim-to-real transfer by training controllers on a distribution of simulated environments, with the goal of achieving robust performance in the real world. Although DR is widely used in practice and is often solved using simple policy gradient (PG) methods, understanding of its theoretical guarantees remains limited ...
