Actuator Fault Diagnosis, State Detection and Fault Tolerant Control for Ground and Rail Vehicles

Dear Colleagues,

Actuators serve as pivotal components, which are responsible for ensuring the precise control and maneuverability in both ground and rail vehicles, directly impacting their operational safety and reliability. The efficient diagnosis of actuator faults allows for the early detection of abnormalities or malfunctions, thus facilitating timely maintenance and repair actions. State detection systems enable the early detection of any deviations from normal operating conditions, which may indicate potential actuator failures or degradations. This proactive approach to monitoring helps prevent catastrophic failures, ensuring that corrective actions can be taken prior to any safety-critical situations arising. The implementation of fault-tolerant control strategies further enhances safety through enabling vehicles to maintain stable and controllable operation, even in the presence of actuator failures or malfunctions.

Currently, one of the main issues faced in this domain is the limited effectiveness of existing diagnostic and control systems in the identification and mitigation of actuator faults in real time. Despite advancements in sensor technology and fault detection algorithms, there remains a gap in achieving robust and reliable fault diagnosis and fault-tolerant control, particularly under varying environmental conditions. Currently, studies that combine advanced sensor fusion techniques, artificial intelligence technology, and distributed control techniques demonstrate great potential. In this background, the purpose of this Special Issue is to establish a platform for researchers and practitioners to share their latest findings, thereby contributing to the advancement of ground and rail vehicles. The topics of interest within the scope of this Special Issue include, but are not limited to, the following:

• Actuator Fault Diagnosis under Multi-Sensor Fusion;
• Data-driven fault diagnosis and failure prediction;
• Real-time detection and dynamic warning;
• Trajectory tracking and collision avoidance control considering actuator failure;
• Control of multi-vehicle platooning systems considering actuator failure;
• Fault-tolerant control of vehicle chassis under actuator failure;
• Active control of vehicle actuators (braking, drive, steering systems, etc.);
• Analysis of vehicle passive safety (e.g., actuator failure analysis, etc.)
• Data-driven state estimation of ground and rail vehicles;
• Data-driven fault-tolerant control of ground and rail vehicles.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Actuators is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
