Title: Sparsity Methods for Systems and Control
Date&Time: 9:30-10:10 JST, Wednesday, March 3

Abstract: In this presentation, we will introduce the maximum hands-off control, also known as L0-optimal control. Maximum hands-off control minimizes the length of the support (i.e. the L0 norm) of the control among all feasible controls. We will see that the L0-optimal control is equivalent to the classical L1-optimal control (also known as minimum-fuel control) under a mild assumption. We also show extension of maximum hands-off control to discrete-valued control and distributed control.

Title: Wasserstein Distributionally Robust Control and Optimization for Ambiguous Stochastic Systems
Date&Time: 13:10-14:00 JST, Tuesday, March 2

Abstract: Standard stochastic control methods assume that the probability distribution of uncertain variables is available. Unfortunately, in practice, obtaining accurate distribution information is a challenging task. To resolve this issue, we investigate the problem of designing a controller that is robust against errors in the empirical distribution obtained from data. The proposed framework using the Wasserstein metric has several salient features, including an out-of-sample performance guarantee, an explicit solution in the LQ setting, and a theoretical connection to the classical H_infty method. We further discuss its MPC variant and application to motion planning and control in risky environments.
