van der Ploeg, C. (author), Smit, R. (author), Teerhuis, A. (author), Silvas, E. (author)Developing safe automated vehicles that can be proactive, safe, and comfortable in mixed traffic requires improved planning methods that are risk-averse and that account for predictions of the motion of other road users. To consider these criteria, in this article, we propose a nonlinear model-predictive trajectory generator scheme, which...conference paper 2022

(author)Self-learning energy management is a promising concept, which optimizes real-world system performance by automated, on-line adaptation of control settings. In this work, the potential of self-learning capabilities related to optimization is studied for energy management in Plug-in Hybrid Electric Vehicles (PHEV).

van der Ploeg, C. (author), Alirezaei, M. (author), van de Wouw, N. (author), Esfahani, P.M. (author)In this article, we propose a tractable nonlinear fault estimation filter along with explicit performance bounds for a class of linear dynamical systems in the presence of both additive and nonlinear multiplicative faults. We consider the case, where both faults may occur simultaneously and through an identical dynamical relationship, a setting...article 2022

van der Sanden, B. (author), Geilen, M. (author), Reniers, M. (author), Basten, T. (author)A key challenge in the synthesis and subsequent analysis of supervisory controllers is the impact of state-space explosion caused by concurrency. The main bottleneck is often the memory needed to store the composition of plant and requirement automata and the resulting supervisor. Partial-order reduction (POR) is a well-established technique...article 2022

(author)An increasing number of tasks is being taken over from the human driver as automated driving technology is developed. Accidents have been reported in situations where the automated driving technology was not able to function according to specifications. As data-driven Artificial Intelligence (AI) systems are becoming more ubiquitous in automated...conference paper 2021

Natali, A. (author), Isufi, E. (author), Coutino, M. (author), Leus, G. (author)Topology identification is an important problem across many disciplines, since it reveals pairwise interactions among entities and can be used to interpret graph data. In many scenarios, however, this (unknown) topology is time-varying, rendering the problem even harder. In this paper, we focus on a time-varying version of the structural...conference paper 2021

Hafkamp, T. (author), van Baars, G. (author), de Jager, B. (author), Etman, P. (author)Technical ceramic parts can be produced by curing ceramic-filled resins in the vat photopolymerization (stereolithography) process. Scaling up to larger ceramic product sizes and higher product quality calls for the integration of more sensing, actuation and closed-loop control solutions while taking a systems engineering approach.

(author)Back support exoskeletons are designed to prevent work-related low-back pain by reducing mechanical loading. For actuated exoskeletons, support based on moments actively produced by the trunk muscles appears a viable approach. The moment can be estimated by a biomechanical model. However, one of the main challenges here is the feasibility of...article 2020

(author)A single-level rule-based model predictive control (RBMPC) scheme is presented for optimizing the energy management of a grid-connected microgrid composed of local production units, renewable energy sources, local loads, and several types of energy storage systems (ESSs). The single-level controller uses two different models that yield different...article 2020

Sanchez, R.M. (author), Nikkhah, S.T. (author), Goswami, D. (author), Heemels, W. (author), Stuijk, S. (author), Basten, T. (author)Pipelining is a promising technique to deal with long delays in control loops, for instance due to intensive data processing. Reconfigurable pipelined control (RPC) is of particular interest, as it has an improved performance compared to a static configuration. We present design and implementation techniques for RPC systems.article 2020

Dresscher, M. (author), Jayawardhana, B. (author)We study a containment control problem (CCP) and a shape control problem (SCP) for systems whose initial condition is a random variable with known distribution.

Engels, W.P. (author), van der Hoek, D. (author), Yu, W. (author), Reyes Baez, R. (author)Many wind turbines are still controlled using gain scheduled, PI(D) controllers. Another option is to use a state feedback controller, such as LQG control. However, for wind turbines that is not straight forward solution, because the system is non-linear and the impact of pitching on the states varies in time. This paper presents a variation on...conference paper 2020

Venkita, S.R. (author), Willemsen, D. (author), Alirezaei, M. (author), Nijmeijer, H. (author)One of the main safety concerns associated with semi-autonomous vehicles is the sharing of control between a human driver and an autonomous driving system. Even with an attentive driver, such switches in control may pose a threat to the safety of the driver and the surrounding vehicles. The aim of this study is to develop an indicator that can...article 2019
