New optimization framework for distributed group-sparse controller design

This paper introduces a unified optimization framework for distributed and sparse feedback linear-quadratic control problems. Researchers propose using the Douglas-Rachford splitting algorithm to solve a nonconvex, nonsmooth optimization problem with an $\ell_0$-penalty. They establish convergence guarantees for this algorithm under specific conditions and also present a projected subgradient descent algorithm that achieves global convergence without these restrictions, potentially serving as a warm-start mechanism for the DR splitting method. Numerical experiments demonstrate the effectiveness of these methods for designing distributed group-sparse controllers. AI
