Parallelizable Real-time MPC with ALADIN

Recently, the Augmented Lagrangian based Alternating Direction Inexact Newton (ALADIN) method has been proposed to solve distributed optimization problems in control applications. This talk focuses on the application of ALADIN to solve MPC problems with long horizons and large-scale interconnected systems. First, we introduce the main idea of ALADIN and its convergence properties for convex and non-convex optimization. Then, we present a real-time variant for MPC, which runs a fix number of ALADIN iterations per sampling time. Furthermore, closed-loop stability is introduced for both the linear and the nonlinear case.
