This paper is to investigate the Proportional Integral (PI) controller that can be used with Indirect Filed Oriented Control (IFOC) mechanism. The PI controller used the parameters generated from the flux and speed estimator based on dq and park transformation of voltage and current inverter output. This estimator represents the sensorless technique that can be applied to the high-power AC motor rated at 20 Hp. The results are in good agreement where the estimator has less than 5% error between the speed estimator and reference speed controller which give faster response based on speed and flux controller with a superior performance on the IM speed. © 2023 IEEE.

Ground plane detection and segmentation techniques can benefit and help improve the accuracy and robustness of a wide range of computer vision applications, from 3D object segmentation and autonomous navigation to mixed and augmented reality. Existing approaches often rely on restrictive assumptions to simplify the problem, such as the ground plane being the largest plane in the scene or the camera location or orientation being ideal. We present a ground plane segmentation technique for real-world 3D indoor scenes where the position and orientation of the sensor are unrestricted and unknown. Our method only requires one 3D point cloud of an indoor scene and assumes that the scene contains at least one surface parallel to the actual ground plane, which is generally true for 3D indoor scenes. We begin by utilizing a voxelized grid downsampling method to enhance the speed of the algorithm. Subsequently, we use K-medoids clustering and an angular-based zone determination technique to identify the ground zone. Next, we divide the ground zone into several clusters using the Euclidean clustering algorithm, and we employ the M-estimator Sample Consensus (MSAC) algorithm to fit the largest plane in each cluster with a specific orientation. Finally, based on the geometric relationship between the fitted planes of the ground zone, we estimate the ground plane, verify it and segment all its associated points using a distance-based approach. We evaluated our method on public and self-generated datasets, in which we positioned a depth sensor at various locations, pitches, and yaws. Our experimental results demonstrate that our proposed method can robustly and efficiently detect and segment the ground plane of complex 3D indoor scenes and supports varied sensor locations and orientations. We evaluate the performance of our proposed method in terms of four conventional metrics: specificity, precision, recall, and F1 score, with average experimental results of 98.28, 95.48, 96.64, a

Purpose - In Business Process Management (BPM), accurate prediction of the next activities is vital for operational efficiency and decision-making. Current Artificial Intelligence (AI)/Machine Learning (ML) models struggle with the complexity and evolving nature of business process event logs, balancing accuracy and interpretability. This paper proposes an entropy-driven model selection approach and DAW-Transformer, which stands for Dynamic Attribute-Aware Transformer, to integrate all attributes with a dynamic window for better accuracy. Design/methodology/approach - This paper introduces a novel next-activity prediction approach that uses process entropy to assess the complexity of event logs and dynamically select the most suitable ML model. A new transformer-based architecture with multi-head attention and dynamic windowing mechanism, DAW-Transformer, is proposed to capture long-range dependencies and utilize all relevant event log attributes. Experiments were conducted on six public datasets, and the performance was evaluated with process entropy. Finding - The results demonstrate the effectiveness of the approach across these publicly available datasets. DAW-Transformer achieved superior performance, especially on high-entropy datasets such as Sepsis exceeding Limited window Multi-Transformers by 4.69% and a benchmark CNN-LSTM-SAtt model by 3.07%. For low-entropy datasets like Road Traffic Fine, simpler, more interpretable algorithms like Random Forest performed nearly as well as the more complex DAW-Transformer and offered better handling of imbalanced data and improved explainability. Originality/ value - This work’s novelty lies in the proposed DAW-Transformer, with a dynamic window and considering all relevant attributes. Also, entropy-driven selection methods offer a robust, accurate, and interpretable solution for next-activity prediction. © 2025, CC BY-NC-SA.

Split Cost Function based Single-Horizon Finite-Set Model Predictive Control for Boost Converter with Loading Current Estimation

IEEE Journal of Emerging and Selected Topics in Power Electronics 2025年

This paper presents a robust single-horizon finite-set model predictive control (FS-MPC) method for controlling the output voltage of boost converters. Unlike the long-horizon FS-MPC approach, which addresses the non-minimum phase (NMP) behavior of the converter by extending the prediction horizon (thereby increasing computational effort), the proposed method ensures stable voltage regulation by incorporating inductor current regulation into the cost function. To achieve this, the desired inductor current is calculated based on input-output power balance theory. Unlike recent studies that require an additional sensor to measure the loading current, this paper develops a loading current estimation approach to eliminate the need for extra current sensors, thereby enhancing the robustness of the proposed FS-MPC method. Additionally, over-current protection, which is typically absent in conventional FS-MPC used for direct voltage regulation, is also incorporated into the proposed method. The conventional cost function is also modified to tackle the NMP behavior more effectively. The performance of the proposed method in regulating the output voltage is evaluated through simulation results. Finally, its effectiveness across a wide range of output power and various load characteristics, including resistive, constant power, and constant current loads, is validated via experimental results. The results demonstrate that the proposed method is not only able to eliminate the overshoot and undershoot, but can also improve the settling time by 41% compared to a well-tuned conventional cascaded PI controller. In addition, the proposed method can reduce the computational burden by 84% compared to the conventional long-horizon FS-MPC approach. © 2013 IEEE.

A significant issue for traffic safety has been drowsy driving for decades. A number of studies have investigated the effects of acute fatigue on spectral power;and recent research has revealed that drowsy driving is associated with a variety of brain connections in a specific cortico-cortical pathway. In spite of this, it is still unclear how different brain regions are connected in drowsy driving at different levels of daily fatigue. This study identified the brain connectivity-behavior relationship among three different daily fatigue levels (low-, median-and high-fatigue) with the EEG data transfer entropy. According to the results, only low-and medium-fatigue groups demonstrated an inverted U-shaped change in connectivity from high performance to poor behavioral performance. In addition, from low-to high-fatigue groups, connectivity magnitude decreased in the frontal region and increased in the occipital region. These study results suggest that brain connectivity and driving behavior would be affected by different levels of daily fatigue. © 2020 IEEE.

Recently, there is more and more integration of photovoltaics (PV) and chargers for electric vehicles (EV) in existing low-voltage (LV) distribution networks. Integration of PVs and EV chargers individually can have a negative effect on the electrical variables of radial distribution networks such as voltages, loading of network elements, losses, etc. However, their simultaneous operation mitigates the negative impact caused by their individual integration. In this paper, different levels of PVs and EV chargers integration are considered and their effect on voltages, loading of cables, losses, as well as power exchange with the external network is studied. Simulation scenarios are implemented in DIgSILENT PowerFactory and power flows are analyzed. According to obtained results, the worst scenarios present two marginal scenarios - without PVs and 100% EV chargers and 100% PVs and without EV chargers. Values of observed parameters in these scenarios have the highest deviations from rated values. In scenario with 50% PV and 25% EV chargers integration, voltage deviation from rated voltage, loading of cables and losses have the lowest value. © 2023 University of Split, FESB.

In this study, an indirect-field-oriented control (IFOC) of an induction motor (IM) was simulated and its speed was estimated using the model reference adaptive system (MRAS) topology of the modified voltage-model-based rotor-flux-oriented current model. As this study dealt with the convolutional neural network (CNN) implemented as the speed controller for the outer-loop control, the inner-loop control used proportional-integral (PI) control to control the current that was fed to the space vector pulse-width modulation (SVPWM) algorithm. The CNN used two inputs based on speed error, and it was designed and trained offline by employing the backpropagation (BP) algorithm to minimize the error between the desired speed and the speed estimated by the estimator and to improve the model's speed-tracking capability when there was an unpredicted speed at the input. The study also used a variable speed trajectory for testing with various speed references to mimic road speed conditions. The results are in good agreement with those of similar studies, and a comparison between the performances of the PI controller and the proposed CNN controller indicated that the CNN controller yielded a superior performance on IM speed. © 2023 IEEE.

Convolutional Neural Networks (CNNs) are efficient tools for pattern recognition applications. They have found applications in wireless communication systems such as modulation classification from constellation diagrams. Unfortunately, noisy channels may render the constellation points deformed and scattered, which makes the classification a difficult task. This paper presents an efficient modulation classification algorithm based on CNNs. Constellation diagrams are generated for each modulation type and used for training and testing of the CNNs. The proposed work depends on the application of Radon Transform (RT) to generate more representative patterns for the constellation diagrams to be used for training and testing. The RT has a good ability to represent discrete points in the spatial domain as curved lines. Several pre-trained networks including AlexNet, VGG-16, and VGG-19 are used as classifiers for modulation type from the spatial-domain constellation diagrams or their RTs. Several simulation experiments are presented in this paper to compare different scenarios for modulation classification at different Signal-to-Noise Ratios (SNRs) and fading channel conditions. © 2022, The Author(s).
