Induction motors are prevalent in many industrial applications due to their robustness, efficiency, and reliability. They are used in various applications, such as pumps, fans, compressors, conveyors, and machine tools. However, faults in induction motors can cause operational and financial losses, and in some cases, they can lead to severe accidents. Therefore, timely and accurate detection of faults is crucial for minimizing the negative impact of these faults. The fault detection methods for induction motors can involve the analysis of various signals such as vibration, current, and voltage. Convolutional neural networks (CNNs) have proven highly effective in many applications but have mainly been applied to two-dimensional data. One-dimensional CNNs offer an excellent alternative for analyzing time sequence datasets since they can work directly with raw signal data without requiring pre- or post-processing. However, the main idea behind 1D-CNNs is to extract spatial features, which can result in the loss of critical temporal features related to time distribution. Recurrent neural networks (RNNs) can effectively capture the temporal dependencies and time distribution in sequences data, making them well-suited to fix the issue. In this paper, we propose a method that combines 1D-CNNs and RNNs called Hybrid 1DCNN-RNN network (HCRN) to analyze the voltage and current signals of a three-phase induction motor. It performs accurate and efficient fault diagnosis, ultimately leading to the more efficient maintenance and reduced downtime for industrial processes.

In this paper, outage performance of hybrid satellite-terrestrial relaying networks using rateless codes (RCs) is evaluated via both simulation and analysis. In the proposed scheme, a satellite (S) transmits encoded packets to a group of terrestrial users (U) with help of a terrestrial station (R). The terrestrial users are suffered from co-channel interference, and they must receive a sufficient number of the encoded packets for the data recovery. This paper analyzes outage probability (OP) at each user and system outage probability (SOP) defined as probability that one of the users cannot collect enough encoded packets after the transmission ends. This paper also investigates impact of number of the users, number of the interference sources, and number of the data transmission of the satellite on the OP and SOP performance.

The complexity of high-dimensional datasets presents significant challenges for machine learning models, including overfitting, computational complexity, and difficulties in interpreting results. To address these challenges, it is essential to identify an informative subset of features that captures the essential structure of the data. In this study, the authors propose Multi-view Sparse Laplacian Eigenmaps (MSLE) for feature selection, which effectively combines multiple views of the data, enforces sparsity constraints, and employs a scalable optimization algorithm to identify a subset of features that capture the fundamental data structure. MSLE is a graph-based approach that leverages multiple views of the data to construct a more robust and informative representation of high-dimensional data. The method applies sparse eigendecomposition to reduce the dimensionality of the data, yielding a reduced feature set. The optimization problem is solved using an iterative algorithm alternating between updating the sparse coefficients and the Laplacian graph matrix. The sparse coefficients are updated using a soft-thresholding operator, while the graph Laplacian matrix is updated using the normalized graph Laplacian. To evaluate the performance of the MSLE technique, the authors conducted experiments on the UCI-HAR dataset, which comprises 561 features, and reduced the feature space by 10-90%. Our results demonstrate that even after reducing the feature space by 90%, the Support Vector Machine (SVM) maintains an error rate of 2.72%. Moreover, the authors observe that the SVM exhibits an accuracy of 96.69% with an 80% reduction in the overall feature space.

This paper presents a backstepping sliding mode control with reaching law based on an extended state observer for tracking control of a quadrotor unmanned aerial vehicle (UAV) under external disturbances. Firstly, a six-degree-of-freedom quadrotor UAV model with disturbances is given. Secondly, the cascade control system is proposed with the Backstepping Sliding Mode controller to track the desired trajectory command under parameter uncertainties. Thirdly, the extended state observer is designed to estimate the external disturbances and rate of the states of the quadrotor UAV to reduce the sensor and increase robustness. The stability of the system is demonstrated by Lyapunov theory and the simulation results via Matlab/Simulink environment.

The development of an energy-sharing algorithm corresponding to the generating capacity of a parallel generator is a mandatory requirement for overload protection and improving power system reliability. As a consequence, the droop control algorithm is considered a potential algorithm to control the production of distributed generators. However, this conventional method often fails to reach the maximum capacity of sources that vary with environmental conditions such as photovoltaic (PV) systems and wind turbines. To overcome this limitation, this study combines the MPPT algorithm with the droop control algorithm for PV grid-connected systems to improve the system power quality. As a result, the P&O algorithms not only enable grid power sharing but also enable MPPT tracking. The simulation results are analyzed to verify the effectiveness of the combined MPPT method.

This study deals with the fault tolerance problem of an active air suspension system considering parametric uncertainties and sprung mass displacement in the event of sensor fault and unmeasured signals. A pneumatic spring is used to set up a quarter of the car model to investigate the flexible stiffness and provide an active force that can suppress chassis vibrations. To approximate unknown nonlinear parameters of air spring actuator dynamics, fuzzy logic systems (FLSs) are used as function approximators. Sensor failure is considered while all system states are assumed to be unmeasured variables. A fuzzy state observer is then designed to approximate the unknown system states and overcome the effective loss of sensor fault. Adaptive fault-tolerant control based on command filter backstepping technique to solve the problem of exploding complexity. To enhance tracking accuracy, this study involves a prescribed performance technique such that the sprung mass displacement is guaranteed between the predefined boundaries. Finally, the effectiveness of the proposed control is verified by comparative simulation examples under the presence of sensor fault and unknown system states.

Projection onto Convex Set (POCS) is a powerful signal processing tool for various convex optimization problems. For non-intersecting convex sets, the simultaneous POCS method can result in a minimum mean square error solution. This property of POCS has been applied to clustering analysis and the POCS-based clustering algorithm was proposed earlier. In the POCS-based clustering algorithm, each data point is treated as a convex set, and a parallel projection operation from every cluster prototype to its corresponding data members is carried out in order to minimize the objective function and to update the memberships and prototypes. The algorithm works competitively against conventional clustering methods in terms of execution speed and clustering error on general clustering tasks. In this paper, the performance of the POCS-based clustering algorithm on a more complex task, embedding clustering, is investigated in order to further demonstrate its potential in benefiting other high-level tasks. To this end, an off-the-shelf FaceNet model and an autoencoder network are adopted to synthesize two sets of feature embeddings from the Five Celebrity Faces and MNIST datasets, respectively, for experiments and analyses. The empirical evaluations show that the POCS-based clustering algorithm can yield favorable results when compared with other prevailing clustering schemes such as the K-Means and Fuzzy C-Means algorithms in embedding clustering problems.
