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.

The reliability of AFM based nanomanipulation is one of the prerequisites for nano fabricating, thus uncertainties of the target nano-particle position need to be controlled within a pointed limits, which lead to two problem to be solved: one is how to describe state uncertainties at every different sample times;the other is how to deduce the next state uncertainty according to the current one. This paper provides a method to construct a stochastic predictive model to covering those problems. In the concrete, the predictive model uses Gaussian and Beta distribution as well as Mont Carlo Method to describe and deduce the state uncertainties respectively. The method is also applied to the process of pushing a nano-particle using AFM. © 2012 IEEE.

Design of Continuous-time controllers using Cartesian Genetic Programming

引用

IFAC Proceedings Volumes 2014年第3期47卷 6982-6987页

作者： Branislav Kadlic Ivan Sekaj Daniel Pernecký Institute of Control and Industrial Informatics Faculty of Electrical Engineering and Information Technology Slovak University of Technology Bratislava Slovak Republic

An evolutionary computation - based design/optimisation approach using the Cartesian Genetic Programming is proposed for non-linear continuous-time process control. It is a simplification of a more general Genetic Programming – based design, which is powerful, but more computationally demanding. The approach is able to produce effective and non-intuitive controllers in the form of a network of interconnected elementary building blocks, which minimize the defined performance index. Each building block performs mathematic operations between its inputs, next it contains gain and an elementary dynamic part as integrator, derivative or unity gain. The proposed design method is demonstrated on water turbine control design, and the results are compared with the genetic algorithm-based PID controller design.

In time delay control systems, the observed information is related to a past instant and using this delayed signal may cause unsatisfactory results in control system applications. This paper deals with how time delay information can be used in reorganizing the rule base so as to improve system performance. Basically, it proposes a new scheme of appropriate shifting of the rule base to compensate the information lag caused by time delay in the system. The parameters affecting the shifting scheme are discussed in detail and the shifting scheme is tabulated with respect to system model parameters. Applications of the new methodology in different systems are simulated and the effectiveness of the scheme is fully illustrated.

This paper presents part of material concerning decentralized control, taught in graduate course control of Complex Systems. We present some basic aspects of decentralized control design concerning stability and performance and illustrate them on a case study: virtual model of a quadruple tank process. control structure selection based on performance relative gain array (PRGA, Hovd, Skogestad, 1992) is used and its ability to evaluate the achievable performance is discussed. Robust stability condition for decentralized control is considered, which provides the upper level on subsystems, thus limiting the performance.
