Constraint-Tightening and Stability in Stochastic Model Predictive Control
TL;DR: In this paper, the authors propose a constraint tightening approach to non-conservatively guarantee recursive feasibility and stability in Stochastic Model Predictive Control (SMPC), and prove asymptotic stability in probability of the minimal robust positively invariant set obtained by the unconstrained LQ-optimal controller.
Journal ArticleDOI
Robust MPC with recursive model update
TL;DR: The main contribution is the introduction of a mathematically rigorous and computationally tractable framework for stabilizing model predictive control with online parameter estimation to improve performance and reduce conservatism.
Journal ArticleDOI
Adaptive Model Predictive Control with Robust Constraint Satisfaction
TL;DR: In this article, a solution based on model predictive control and set-membership system identification is presented for adaptive control for constrained, linear systems and a computationally tractable solution which uses observations of past state and input trajectories to update the model and improve control performance while maintaining guaranteed constraint satisfaction and recursive feasibility.
Journal ArticleDOI
Stochastic MPC with offline uncertainty sampling
TL;DR: The paper highlights the structural difference between online and offline sampling and provides rigorous bounds on the number of samples needed to guarantee chance constraint satisfaction and allows to suitably tighten the constraints to guarantee robust recursive feasibility when limits on the uncertain variables are provided.
Journal ArticleDOI
Robust economic Model Predictive Control using stochastic information
TL;DR: A new tube-based robust economic MPC scheme for linear time-invariant systems subject to bounded disturbances with given distributions is developed by using the error distribution in the predictions of the finite horizon optimal control problem to incorporate stochastic information.
