Gaussian Process Dual MPC using Active Inference: An Autonomous Vehicle Usecase
Mohammad Mahmoudi Filabadi, Guillaume Crevecoeur, Tom Lefebvre
Designing controllers under uncertainty requires balancing the need to explore system dynamics with the requirement to maintain reliable control performance. Dual control addresses…
Unifying Entropy Regularization in Optimal Control: From and Back to Classical Objectives via Iterated Soft Policies and Path Integral Solutions
Ajinkya Bhole, Mohammad Mahmoudi Filabadi, Guillaume Crevecoeur +1
This paper develops a unified perspective on several optimal control formulations through the lens of Kullback-Leibler (KL) regularization. We propose a central problem that separa…
How to Capture Human Preference: Commissioning of a Robotic Use-Case via Preferential Bayesian Optimisation
Sander De Witte, Jeroen Taets, Andras Retzler +2
The popularity of Bayesian Optimization (BO) to automate or support the commissioning of engineering systems is rising. Conventional BO, however, relies on the availability of a sc…
Differential Flatness of Quasi-Static Slider-Pusher Models with Applications in Control
Sander De Witte, Tom Lefebvre, Thomas Neve +2
This paper investigates the dynamic properties of planar slider-pusher systems as a motion primitive in manipulation tasks. To that end, we construct a differential kinematic model…
Dual Control Reference Generation for Optimal Pick-and-Place Execution under Payload Uncertainty
Victor Vantilborgh, Hrishikesh Sathyanarayan, Guillaume Crevecoeur +2
This work addresses the problem of robot manipulation tasks under unknown dynamics, such as pick-and-place tasks under payload uncertainty, where active exploration and(/for) onlin…
Probabilistic Latent Variable Modeling for Dynamic Friction Identification and Estimation
Victor Vantilborgh, Sander De Witte, Frederik Ostyn +2
Precise identification of dynamic models in robotics is essential to support control design, friction compensation, output torque estimation, etc. A longstanding challenge remains…
