Implementation of soft-constrained MPC for Tracking using its semi-banded problem structure

no code implementations7 Mar 2024 Victor Gracia, Pablo Krupa, Daniel Limon, Teodoro Alamo

Model Predictive Control (MPC) is a popular control approach due to its ability to consider constraints, including input and state restrictions, while minimizing a cost function.

Efficient implementation of MPC for tracking using ADMM by decoupling its semi-banded structure

no code implementations15 Feb 2024 Victor Gracia, Pablo Krupa, Daniel Limon, Teodoro Alamo

Model Predictive Control (MPC) for tracking formulation presents numerous advantages compared to standard MPC, such as a larger domain of attraction and recursive feasibility even when abrupt changes in the reference are produced.

Learning disturbance models for offset-free reference tracking

no code implementations18 Dec 2023 Pablo Krupa, Mario Zanon, Alberto Bemporad

This work presents a nonlinear MPC framework that guarantees asymptotic offset-free tracking of generic reference trajectories by learning a nonlinear disturbance model, which compensates for input disturbances and model-plant mismatch.

Harmonic model predictive control for tracking periodic references

no code implementations25 Oct 2023 Pablo Krupa, Daniel Limon, Alberto Bemporad, Teodoro Alamo

Harmonic model predictive control (HMPC) is a recent model predictive control (MPC) formulation for tracking piece-wise constant references that includes a parameterized artificial harmonic reference as a decision variable, resulting in an increased performance and domain of attraction with respect to other MPC formulations.
