Repetitive processes propagate information in two separate directions, one of which is temporal and the other can be spatial. A repetitive process makes a series of sweeps, or passes, through a set of dynamics over this finite duration and when each is complete the process resets. Moreover, the output produced on the previous pass explicitly contributes to the dynamics produced on the next one. Hence they can also be viewed as a class of periodic systems. They also pose control problems that cannot be solved by standard systems control theory and design algorithms. This paper gives new results on the application of the repetitive process control theory to the analysis of ladder networks. © IFAC.

A control systems engineering approach, employing a two-level overall system architecture and different but compatible formalisms for system representation on the upper and lower levels, has been investigated in detail. One design alternative is based on employing fuzzy-system approximators and solving for the adaptive tracking of the given, arbitrary, desired system outputs. The other alternative is based on state equations of composite systems and the use of neural-network approximators to deal with uncertainties and control adaptation. In both alternatives similarity property of subsystems has been exploited. Both designs can be implemented within the standard computer process control technology, and are therefore believed to be promising in applied systems engineering. Copyright © 2003 IFAC.

Novel original robust gain-scheduled controller design for individualized type 1 diabetes mellitus (T1DM) subject model is presented in this paper. For controller design an LPV model is created from insulin-glucose subsystem based on Bergman’s minimal model with subcutaneous insulin absorption and absorption of digested carbohydrates. Identification was performed on pharmacokinetics and pharmacodynamics characteristics of administered insulin and data collected from continuous glucose monitoring (CGM) system. The controller design approach guarantees the closed-loop stability and cost for all scheduled parameter changes. Simulation results show the benefits of the proposed approach.

The 3D LiDAR place recognition aims to estimate a coarse localization in a previously seen environment based on a single scan from a rotating 3D LiDAR sensor. The existing solutions to this problem include hand-crafted point cloud descriptors (e.g., ScanContext, M2DP, LiDAR IRIS) and deep learning-based solutions (e.g., PointNetVLAD, PCAN, LPD-Net, DAGC, MinkLoc3D), which are often only evaluated on accumulated 2D scans from the Oxford RobotCar dataset. We introduce MinkLoc3D-SI, a sparse convolution-based solution that utilizes spherical coordinates of 3D points and processes the intensity of 3D LiDAR measurements, improving the performance when a single 3D LiDAR scan is used. Our method integrates the improvements typical for hand-crafted descriptors (like ScanContext) with the most efficient 3D sparse convolutions (MinkLoc3D). Our experiments show improved results on single scans from 3D LiDARs (USyd Campus dataset) and great generalization ability (KITTI dataset). Using intensity information on accumulated 2D scans (RobotCar Intensity dataset) improves the performance, even though spherical representation doesn’t produce a noticeable improvement. As a result, MinkLoc3D-SI is suited for single scans obtained from a 3D LiDAR, making it applicable in autonomous vehicles. © 2021, CC BY-SA.

In this paper we study state-space realizations of Linear and Time-Invariant (LTI) systems. Motivated by biochemical reaction networks, Gonçalves and Warnick have recently introduced the notion of a Dynamical Structure Functions (DSF), a particular factorization of the system's transfer function matrix that elucidates the interconnection structure in dependencies between manifest variables. We build onto this work by showing an intrinsic connection between a DSF and certain sparse left coprime factorizations. By establishing this link, we provide an interesting systems theoretic interpretation of sparsity patterns of coprime factors. In particular we show how the sparsity of these coprime factors allows for a given LTI system to be implemented as a network of LTI sub-systems. We examine possible applications in distributed control such as the design of a LTI controller that can be implemented over a network with a pre-specified topology. ©2013 IEEE.

This paper explores the efficacy of two distinct approaches in computer vision, particularly in intelligent sports training systems. Our focus is on the development and comparison of two methodologies for image recognition in a basketball score detection system, named "Koško." The first approach uses a pre-trained model with two combined datasets in the training phase. This method leverages diverse data to enhance the model’s ability to generalize and accurately recognize scores in basketball games. In contrast, the second approach fine-tunes a model initially trained on one dataset with a subsequent second dataset. Rooted in recent transfer learning studies, this method shows that selectively fine-tuning a subset of layers or customizing learning rates can significantly improve robustness to out-of-distribution (OOD) data. By enforcing weight projections, this approach aims to maintain the generalization capabilities of the pre-trained models while adapting to the new dataset. Our research balances precise score detection and pragmatic system development, contributing to intelligent sports training systems. This work highlights the feasibility of combining machine learning and vision-based methodologies to advance sports training systems. Research on basketball score detection using the YOLOv8n model shows the pre-trained model achieved 93.75% accuracy and a 3% false positive rate, outperforming the fine-tuned model’s 88.71% accuracy and 5% false positive rate. By evaluating both networks, this study aims to provide clear strategies for implementing computer vision systems in sports, particularly in the dynamic environment of basketball. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

One of the prerequisites for AFM based nanomanipulation is that the tip position can be controlled accurately, while this prerequisite is still hindered by the large model uncertainties aroused from PZT nonlinearity such as hysteresis and creep. In this paper, an Extended Prandtl-Ishlinskii (EPI) model is proposed to solve these problems. The main advantage of EPI model over conventional PI model is that the EPI model can compensate the positioning error caused by hysteresis and creep simultaneously through adopting the new adaptive basic operator. The experimental results demonstrate the effectiveness and validity of EPI model in depicting the PZT hysteresis and creep prosperities. © 2010 IEEE.

The goal to control the dynamics of high-rise buildings either to ameliorate the damage or prevent their destruction when subject to an earthquake excitation has been subject of extensive research. All known control designs have advantages and disadvantages as well as operating limits. The application of sliding-mode control to controlling earthquake induced vibrations of a multi-story structural system as an active seismic compensation plus base isolation has been investigated. The performance has been compared to the one of traditional industrial controls, and relevant conclusions drawn. Simulation results, carried out using El Centro earthquake acceleration, have shown that the sliding mode control can decrease significantly displacements of the floors. Copyright © 2006 IFAC.

Electric vehicle (EV) technology has come up with showing many alternative solutions to the issues mainly caused due to the carbon emissions by the conventional vehicles and hence grabbed a massive attention of the entire world. Furthermore, while electric vehicles (EVs) have their own advantages, they also have a number of drawbacks, such as concerns with heat management, battery management, health degradation, integration of power electronic conversions, charging and discharging issues, etc. The estimation of SOC and RUL is quiet difficult task as these are highly dependent of temperature measurements. Hence, thermal management is the key challenging task that to be considered in EVs. A comprehensive discussion of battery management systems, including their significant attributes has been addressed in this article.
