Mass Loss and Displacement Modeling for Multi-Axis Milling

no code implementations12 Nov 2023 Adrian Karl Rüppel, Patrick Ochudlo, Mathias Bickel, Sebastian Stemmler, Thomas Bergs, Dirk Abel

During the cutting process, material of the workpiece is continuously being removed by the cutting tool, which results in a reduction of mass as well as a displacement in the center of the workpiece mass.

Vehicle Cabin Climate MPC Parameter Tuning Using Constrained Contextual Bayesian Optimization (C-CMES)

no code implementations5 Oct 2023 David Stenger, Tim Reuscher, Heike Vallery, Dirk Abel

Model Predictive Controllers (MPCs) have shown promising results in achieving temperature tracking in vehicle cabins and may improve upon model-free control performance.

Automated Tuning of Nonlinear Kalman Filters for Optimal Trajectory Tracking Performance of AUVs

no code implementations7 Apr 2023 Maximilian Nitsch, David Stenger, Dirk Abel

To enable a fair comparison, filter parameters are auto-tuned with Bayesian optimization (BO) for open and closed-loop performance, which is novel in AUV navigation.

Benchmark of Bayesian Optimization and Metaheuristics for Control Engineering Tuning Problems with Crash Constraints

no code implementations4 Nov 2022 David Stenger, Dirk Abel

Results indicate that deterministic noise, low multimodality, and substantial areas with infeasible parametrizations (crash constraints) characterize control engineering tuning problems.

Reduction and Observer Design for a Grey-Box Model in Continuous Pharmaceutical Manufacturing

no code implementations13 Jun 2022 Ahmed Elkhashap, Dirk Abel

It is shown that the ROM could reproduce the FOM states accurately with a relative mean square error below $0. 3\,\%$ for the experimental data simulation.

Joint Constrained Bayesian Optimization of Planning, Guidance, Control, and State Estimation of an Autonomous Underwater Vehicle

no code implementations29 May 2022 David Stenger, Maximilian Nitsch, Dirk Abel

Our objective is to automatically tune these parameters with respect to arbitrary high-level control objectives within different operational scenarios.

Machine Learning Integrated with Model Predictive Control for Imitative Optimal Control of Compression Ignition Engines

no code implementations1 Apr 2022 Armin Norouzi, Saeid Shahpouri, David Gordon, Alexander Winkler, Eugen Nuss, Dirk Abel, Jakob Andert, Mahdi Shahbakhti, Charles Robert Koch

One solution is the use of machine learning (ML) and model predictive control (MPC) to minimize emissions and fuel consumption, without adding substantial computational cost to the engine controller.

Model Predictive Control

Deep Learning based Model Predictive Control for Compression Ignition Engines

no code implementations31 Mar 2022 Armin Norouzi, Saeid Shahpouri, David Gordon, Alexander Winkler, Eugen Nuss, Dirk Abel, Jakob Andert, Mahdi Shahbakhti, Charles Robert Koch

Machine learning (ML) and a nonlinear model predictive controller (NMPC) are used in this paper to minimize the emissions and fuel consumption of a compression ignition engine.

Towards Real-Time Monitoring and Control of Water Networks

no code implementations12 Jan 2022 Ahmed Elkhashap, Daniel Rüschen, Dirk Abel

A reduced order model (ROM) with a 50 mm spatial resolution, i. e. 1200 discretization points, is constructed and utilized as the identification model for a single path of the test bench.

Robust state and protection-level estimation within tightly coupled GNSS/INS navigation system

no code implementations19 Mar 2021 Shuchen Liu, Kaizheng Wang, Dirk Abel

In autonomous applications for mobility and transport, a high-rate and highly accurate vehicle-state estimation is achieved by fusing measurements of global navigation satellite systems (GNSS) and inertial sensors.

Depth Camera Based Particle Filter for Robotic Osteotomy Navigation

no code implementations24 Oct 2019 Tim Übelhör, Jonas Gesenhues, Nassim Ayoub, Ali Modabber, Dirk Abel

Active surgical robots lack acceptance in clinical practice, because they do not offer the flexibility and usability required for a versatile usage: the systems require a large installation space or a complicated registration step, where the preoperative plan is aligned to the patient and transformed to the base frame of the robot.
