Application Aspects of Active-set Quadratic Programming in Real-time Embedded Model Predictive Vibration Control

IFAC-PapersOnLine 2017年第1期50卷 11625-11631页

作者： Batista G. Takács G. Rohal’-Ilkiv B. Institute of Automation Measurement and Applied Informatics Faculty of Mechanical Engineering Slovak University of Technology in Bratislava Slovakia

This paper presents a study on the practical utilization of various microcontroller units (MCU) for model predictive vibration control, using an online active-set quadratic programming solver. The implementation properties of various 32bit MCUs are assessed in experiment. An analysis of memory requirements is made on all investigated MCUs, along with evaluating timing requirements for a simple vibration control problem. These tests show execution time limits, memory footprint, and convergence under different circumstances. The experiments investigate the effects of hot-starting, numerical precision and the use of the floating-point unit (FPU) of the MCU. The results presented in this paper show that the hot-starting technique used with double precision data format is preferable, since computation using single precision numeric format fails to converge on many instances. Although it is tempting to reduce numerical precision to extend the maximal horizon stored in the volatile and nonvolatile memories and to cut execution times, the numerical stability of the investigated online active-set quadratic programming solver is heavily affected. Moreover, it has been found that a built-in FPU does not have significant impact on performance; the presence of this hardware feature does not significantly aid the implementation of model predictive control for the case study presented here. © 2017

Early and accurate diagnosis of brain tumors is crucial to improving patient outcomes and optimizing treatment strategies. Long-term brain injury results from aberrant proliferation of either malignant or nonmalignant tissues in the brain. MRIs, or magnetic resonance imaging, are one of the most used approaches for detecting brain tumors. Professionals physically evaluate people after they have had MRI filtering, the process of enhancing MRI scans for radiologist interpretation, to establish if they have a brain tumor. Because different specialists use different frames to make judgments on the same MRI image, their analyses may yield contradictory results. Furthermore, simply detecting a tumor is insufficient. Inconsistent diagnoses can lead to delays in treatment, impacting survival rates and quality of care. It is also crucial to diagnose the patient's tumor so that treatment can begin as soon as possible. In this research, we investigate the multi-class classification of brain tumors utilizing a cutting-edge methodology that includes feature extraction from pictures using the DieT Transformer model, dimensionality reduction with PCA, and feature selection using the ADE algorithm. The proposed model, known in the publication as ADE_DieT, obtained an accuracy of 96.09 %. In addition, this article analyzes the performance of various pre-trained models, including MobileNetV3, NasNet, ResNet50, VGG16, VGG19, and DeiT. The proposed approach shortens the time required for manual diagnosis by clinicians by assisting in the rapid and accurate identification of brain tumors using MRI data. In oncology, this is important since it allows for early treatment. Integrating ADE_DieT into clinical workflows can support radiologists by reducing diagnosis time and enhancing diagnostic consistency. © 2024 The Authors

This study presents a cancer dynamics model incorporating a fractal-fractional operator with a Mittag-Leffler kernel to capture complex interactions among cancer cells, tumor suppressor cells, immune cells, and oncolytic viruses. The model aims to enhance understanding of tumor-immune dynamics and improve treatment strategies. The existence and uniqueness of the solution are established using fixed point theory under the Lipschitz condition. Lyapunov stability of the system is also analyzed in the context of the fractal-fractional operator. To address chaotic behavior in cancer progression, chaos and Proportional-Integral-Derivative (PID) control techniques are implemented. These control methods effectively stabilize the system and regulate treatment administration. Numerical simulations illustrate the influence of fractional-order derivatives on tumor suppression and immune response, confirming the model's effectiveness in reflecting real-world cancer dynamics. © 2025 The Author(s)

This paper presents an approach intended for tracking of biological non-stationary signals. The proposed approach utilizes a Kalman filter autoregressive model together with a method for estimation of covariance matrices of the uncorrelated process noise and measurement noise. The method was tested in simulations, where the ability of tracking of a class of time varying autoregressive processes was the subject of our interest. The obtained results are promising in the meaning that the suggested algorithm is suitable to track the time varying autoregressive processes with sufficient accuracy. © 2015 IEEE.

作者： Polóni, Tomá Rohal-Ilkiv, Boris Arne Johansen, Tor Department of Aerospace Engineering University of Michigan Ann Arbor United States Institute of Automation Measurement and Applied Informatics Faculty of Mechanical Engineering Slovak University of Technology Bratislava Slovakia Department of Engineering Cybernetics Norwegian University of Science and Technology Trondheim Norway

This paper presents a nonlinear numerical observer for accurate position, velocity and attitude (PVA) estimation including the accelerometer bias and gyro bias estimation. The Moving Horizon Observer (MHO) processes the accelerometer, gyroscope and magnetometer measurements from the Inertial Measurement Unit (IMU) and the position and velocity measurements from the Global Navigation Satellite System (GNSS). The nonlinear measurement equations with the rotation matrix, expressed through the quaternion parametrization, in combination with the state-space rigid body kinematic model of translational and rotational motion is the subject of optimization defined on a receding data window. The gradient-based trust-region method is applied to solve the MHO's nonlinear least-squares criterion. The MHO is tesed off-line in the numerical experiment involving the experimental flight data from a light fixed-wing aircraft. This study demonstrates the quality of the MHO computations with the comparison of the reference filter, the multiplicative Extended Kalman Filter (EKF). © 2015, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.

As the cast strand moves through the secondary cooling zone in a continuous casting machine, the secondary cooling zone is typically separated into a number of zones to control the cooling rate. The secondary cooling zone’s primary tasks in terms of heat transfer are to deliver the amount of water necessary to completely solidify a strand within the parameters of continuous casting operation, such as steel grade and casting speed, or the system can the ability to control the strand’s thermal conditions from below the mold to the end of the secondary cooling zone, such as the required strand surface temperature. In this paper, the controller parameter optimization process will be done in Simulink using a robust control toolbox, and a robust method based on IMC controllers will be selected for control synthesis with the consideration of the controlled system uncertainty, and the result will be displayed as temperature fields, which represent the system with distributed parameters. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

To establish trust in the measurement results, the metrological traceability of the measuring devices utilized must be ensured. This can be accomplished by confirming or calibrating the instruments. In reality, the information received during calibration is given in the traditional calibration certificate, and the user of the certified instrument decides how to utilize it in the measurement. Here comes the role of the digital calibration certificate that unlocks several features of this kind of calibration certificate that the user can use during its own measurements. In our case, the digital calibration certificate provides the option of supplying a large amount of additional data that may be usefully employed in various different tests. There are several methods for solving this kind of a problem. The paper discusses one method to this problem which is called the "Monte Carlo Method" and shows it using a specific case to give you a closer sight of this problem. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
