Special Issue Information

Dear Colleagues,

In the last decade, we have witnessed the rapid development of sensors and an increasing number of studies on making full use of sensory data for various applications, e.g., human sensing, environment sensing, and underwater sensing. Dealing with the collected signal which bears inherent noises due to the hardware imperfections or external interference from the environment is fundamental to achieve a high-performance sensing result. Recent advances in model-driven and data-driven signal processing have made great efforts in tackling the noisy and error-prone signals.

This Special Issue aims to collect original research and review articles on technologies, solutions, applications, and new challenges that are related to signal and sensory data processing. Potential topics include, but are not limited to, the following:

  • Model-driven signal processing methods;
  • Data-driven signal processing methods;
  • Radio frequency signal processing;
  • Acoustic signal processing;
  • Wearable sensor signal processing;
  • Mobile sensor signal processing;
  • Time-series signal processing;
  • Signal processing for human sensing applications;
  • Signal processing for environment sensing applications;
  • Signal processing in security-related applications;
  • Sensory data management and analytics, including quality, integrity, and trustworthiness;
  • Sensor signal processing for resource-constrained and mobile platforms;
  • Novel embedded machine learning algorithms on sensor data.

Accurately forecasting electrical signals from three-phase Direct Torque Control (DTC) induction motors is crucial for achieving optimal motor performance and effective condition monitoring. However, the intricate nature of multiple DTC induction motors and the variability in operational conditions present significant challenges for conventional prediction methodologies. To address these obstacles, we propose an innovative solution that leverages the Fast Fourier Transform (FFT) to preprocess simulation data from electrical motors. A Bidirectional Long Short-Term Memory (Bi-LSTM) network then uses this altered data to forecast processed motor signals. Our proposed approach is thoroughly examined using a comparative examination of cutting-edge forecasting models such as the Recurrent Neural Network (RNN), Long Short-Term Memory (LSTM), and Gated Recurrent Unit (GRU). This rigorous comparison underscores the remarkable efficacy of our approach in elevating the precision and reliability of forecasts for induction motor signals. The results unequivocally establish the superiority of our method across stator and rotor current testing data, as evidenced by Mean Absolute Error (MAE) average results of 92.6864 and 93.8802 for stator and rotor current data, respectively. Additionally, compared to alternative forecasting models, the Root Mean Square Error (RMSE) average results of 105.0636 and 85.7820 underscore reduced prediction loss. Full article
