Cascaded control structures are prevalent in industrial systems with many disturbances to obtain stable control but are cumbersome and challenging to tune. In this work, we propose cascaded constrained residual reinforcement learning (RL), an intuiti

In this article, we present a generalized view on Path Integral Control (PIC) methods. PIC refers to a particular class of policy search methods that are closely tied to the setting of Linearly Solvable Optimal Control (LSOC), a restricted subclass o

This paper treats a special case of the Imitation from Observations (IfO) problem. IfO is a generalisation of Imitation Learning from state-only demonstrations. Our treatment of IfO considers the case of feature-only demonstrations. This means that t

In this paper, we investigate two ideas in the context of the interpolation-based optimization paradigm tailored to derivative-free black-box optimization problems. The proposed architecture maintains a radial basis function interpolation model of th

In this work, we show that the differential kinematics of slider–pusher systems are differentially flat assuming quasi-static behavior and frictionless contact. Second, we demonstrate that the state trajectories are invariant to time-differential t

Polynomial Chaos Expansions (PCEs) offer an efficient alternative to assess the statistical properties of a model output taking into account the statistical properties of several uncertain model inputs, particularly, under the restriction of probing

Industrial robots can collide due to malfunctioning, wrong user input or unforeseen changes in the environment in which they operate. Different solutions exist to minimize the damage caused by a collision, either absorbed by the environment or by the
