This paper presents an introduction on six distributed optimization algorithms and compares their properties in the context of distributed MPC for linear systems with convex quadratic objectives and polytopic constraints. In particular, dual decomposition, the alternating direction method of multipliers, a distributed active set method, an essentially decentralized interior point method, and Jacobi iterations are discussed. Numerical examples illustrate the challenges, the prospect, and the limits of distributed MPC with inexact solutions.en2196-677X20224317330De Gruyterhttps://creativecommons.org/licenses/by/4.0/active set methodsADMMconjugate gradientsdistributed optimizationdual decompositionfast gradientsinterior point methodsJacobi iterationsmodel predictive controlEngineering and Applied OperationsJournal Article10.15480/882.919010.1515/auto-2021-011210.15480/882.9190Journal Article
