Special Issue Information

Dear Colleagues,

Automation of industrial processes (smart factories, collaborative robots, Industry 4.0) and everyday life (smart buildings, automated driving) play an increasing role in the advancement of modern societies. Due to the complexity of automated installations, the prevention of safety hazards and huge production losses require the detection and identification of any kind of fault, as early as possible, and to minimize their impacts by implementing real-time fault detection (FD) and fault-tolerant (FT) operations systems. Therefore, FD and FT technologies have attracted an increasing amount of research and industrial attention in recent years. Modern FD and FT schemas demand high-volume, high-quality information from multiple types of sensor data, but sensors are also subject to failure, which must be included in the diagnostic systems. The integration of distributed sensor networks in model-based, signal-based, knowledge-based, and hybrid/active diagnostic systems is a challenging issue, which requires techniques from a broad set of disciplines, such as artificial intelligence, adaptive observers design, statistical estimation, data dimension reduction techniques, etc. Robust active and passive FT approaches that can tolerate discontinuities and errors in the flow of sensors data are needed to increase the reliability of automated systems. A particular, a growing trend in recent years has been the use of electric machines and electronic drives as a source of signals for FD/FT industrial systems, acting as sensors.

We invite academia and industry researchers to submit original and unpublished manuscripts to this Special Issue that develop research works related to these topics.

The goal of the Special Issue is to publish the most recent research results and industrial applications of sensors in FD and FT methods. Topics suited for this Special Issue include, but are not limited to: 

  • Data-driven and model-based sensor fault diagnosis.
  • Self-healing, self-organizing, self-adaptive, automatic recovery of sensor networks.
  • Integration of high-volume sensor data in the design of fault diagnosis and fault-tolerant control.
  • Sensors in advanced FD/FT applications in different industrial sectors.
  • Methods, concepts and performance assessment for improving FD/FT existing in industrial applications.
  • Electrical drives as sensors in industrial processes.
  • Sensors systems for fault tolerant electrical drives.

In modern systems with induction motors (IM), in addition to precision, it is also very important to ensure the highest possible reliability and safety. To ensure the above, information about the stator current value is required. If the current sensor (CS) fails, a redundant sensor or an algorithmic solution can be used. The Luenberger observer (LO) can be used to estimate the lost stator current without increasing the cost of the drive system. However, this solution is based on the mathematical model of IM, which is sensitive to its parameters. Therefore, this paper presents a modified LO (MLO) and investigates the effect of a coefficient in the error gain matrix on improving robustness to changes in the IM parameters. As shown by extensive studies, the proposed solution has significantly reduced the influence of the IM parameters on the accuracy of the stator current estimation, which has not been previously reported in the known literature.

This paper deals with the LPV control of a three-axis gimbal including fault-tolerant capabilities. First, the derivation of an analytical model for the considered system based on the robotics Serial-Link (SL) theory is derived. Then, a series of simplifications that allow obtaining a quasi-LPV model for the considered gimbal is proposed. Gain scheduling LPV controllers with PID structure are designed using pole placement by means of linear matrix inequalities (LMIs). Moreover, exploiting the sensor redundancy available in the gimbal, a virtual-sensor-based fault tolerant control (FTC) strategy is proposed. This virtual sensor uses a Recursive Least Square (RLS) estimation algorithm and an LPV observer for fault detection and estimation. Finally, the proposed LPV control scheme including the virtual sensor strategy is tested in simulation in several scenarios. Full article
