Computational modeling and simulation are powerful tools for the assessment of medical device performance and safety, particularly for in silico clinical trials for automated medic…
LPV Updates for Sequentially Linearized Moving Horizon Estimation of Nonlinear Systems
Jiaxin Ji, Jan Heiland, Dimitrios S. Karachalios +1
Moving horizon estimation (MHE) provides high precision state estimation for nonlinear systems, but it is often limited by the substantial computational demands of solving a nonlin…
Efficient Nonlinear MPC by Leveraging LPV Embedding and Sequential Quadratic Programming
Dimitrios S. Karachalios, Hossam S. Abbas
In this paper, we present efficient solutions for the nonlinear program (NLP) associated with nonlinear model predictive control (NMPC) by leveraging the linear parameter-varying (…
Stochastic Error Bounds in Nonlinear Model Predictive Control with Gaussian Processes via Parameter-Varying Embeddings
Dimitrios S. Karachalios, Hossam S. Abbas
This study utilized the Gaussian Processes (GPs) regression framework to establish stochastic error bounds between the actual and predicted state evolution of nonlinear systems. Th…
Obstacle Avoidance of Autonomous Vehicles: An LPVMPC with Scheduling Trust Region
Maryam Nezami, Dimitrios S. Karachalios, Georg Schildbach +1
Reference tracking and obstacle avoidance rank among the foremost challenging aspects of autonomous driving. This paper proposes control designs for solving reference tracking prob…
Closed-Loop Identification and Tracking Control of a Ballbot
Tobias Fischer, Dimitrios S. Karachalios, Ievgen Zhavzharov +1
Identifying and controlling an unstable, underactuated robot to enable reference tracking is a challenging control problem. In this paper, a ballbot (robot balancing on a ball) is…
