Robust Optimal Control for Nonlinear Systems with Parametric Uncertainties via System Level Synthesis

1 code implementation3 Apr 2023 Antoine P. Leeman, Jerome Sieber, Samir Bennani, Melanie N. Zeilinger

The proposed approach jointly optimizes a nominal nonlinear trajectory and an error feedback, requiring minimal offline design effort and offering low conservatism.

Asynchronous Computation of Tube-based Model Predictive Control

no code implementations24 Nov 2022 Jerome Sieber, Andrea Zanelli, Antoine P. Leeman, Samir Bennani, Melanie N. Zeilinger

Tube-based model predictive control (MPC) methods bound deviations from a nominal trajectory due to uncertainties in order to ensure constraint satisfaction.

Model Predictive Control

Finite Horizon Worst-Case Analysis of Linear Time-Varying Systems Applied to Launch Vehicle

no code implementations24 Nov 2021 Felix Biertümpfel, Nantiwat Pholdee, Samir Bennani, Harald Pfifer

A condition for the worst-case gain of such an interconnection can be formulated using dissipation theory as a parameterized Riccati differential equation, which depends on the chosen IQC multiplier.

System Level Disturbance Reachable Sets and their Application to Tube-based MPC

no code implementations5 Nov 2021 Jerome Sieber, Andrea Zanelli, Samir Bennani, Melanie N. Zeilinger

Tube-based model predictive control (MPC) methods leverage tubes to bound deviations from a nominal trajectory due to uncertainties in order to ensure constraint satisfaction.

Optimal Science-time Reorientation Policy for the Comet Interceptor Flyby via Sequential Convex Programming

no code implementations19 May 2021 Valentin Preda, Andrew Hyslop, Samir Bennani

This paper introduces an algorithm to perform optimal reorientation of a spacecraft during a high speed flyby mission that maximizes the time a certain target is kept within the field of view of scientific instruments.

Autonomous parafoil precision landing using convex real-time optimized guidance and control

1 code implementation3 May 2021 Antoine Leeman, Valentin Preda, Irene Huertas, Samir Bennani

To overcome the limitations of current parafoil precision landing capabilities, an efficient real-time convex optimized guidance and control strategy is presented.

A System Level Approach to Tube-based Model Predictive Control

no code implementations3 Mar 2021 Jerome Sieber, Samir Bennani, Melanie N. Zeilinger

Robust tube-based model predictive control (MPC) methods address constraint satisfaction by leveraging an a priori determined tube controller in the prediction to tighten the constraints.
