Douglas-Rachford Splitting for Group-Sparse Feedback Linear-Quadratic Control
Lechen Feng, Xun Li, Yuan-Hua Ni
In this paper, we study the distributed linear quadratic problem with fixed communication topology (DFT-LQ) and the sparse feedback linear quadratic (SF-LQ) problem through a unifi…

A Convex Optimization Approach to Model-Free Inverse Optimal Control with Provable Convergence
Meiling Yu, Lechen Feng, Lei Jiang +1
Inverse Optimal Control (IOC) aims to infer the underlying cost functional of an agent from observations of its expert behavior. This paper focuses on the IOC problem within the co…

Two-Timescale Optimization Framework for Sparse-Feedback Linear-Quadratic Optimal Control
Lechen Feng, Yuan-Hua Ni, Xuebo Zhang
A -guaranteed sparse-feedback linear-quadratic (LQ) optimal control with convex parameterization and convex-bounded uncertainty is studied in this paper, where $\ell…
