Bounding the Error of Value Functions in Sobolev Norm Yields Bounds on Suboptimality of Controller Performance
Morgan Jones, Matthew Peet
Optimal feedback controllers for nonlinear systems can be derived by solving the Hamilton-Jacobi-Bellman (HJB) equation. However, because the HJB equation is a nonlinear partial di…

Approximate Projections onto the Positive Semidefinite Cone Using Randomization
Morgan Jones, James Anderson
This paper presents two algorithms that compute approximate Positive Semidefinite (PSD) projections of real symmetric matrices using Randomized Numerical Linear Algebra (RNLA). Cla…
