RESEARCH ON SEMI-ACTIVE CONTROL METHODS FOR STADDLE MONORAIL′S PANTOGRAPH WITH SLIDING MODE VARIABLE STRUCTURE (MT)

open access: yesJixie qiangdu, 2023
Staddle monorail use rigid catenary, which often produce strong rigid vibrations and violent fluctuations in contact forces affecting pantograph receiving quality and service life during operation.

Adaptive and Robust Fault-Tolerant Tracking Control of Contact force of Pantograph-Catenary for High-Speed Trains [PDF]

open access: yesIFAC-PapersOnLine, 2015
Abstract This paper presents a modified multi-body dynamic model and a linear time-invariant model with actuator faults (loss of effectiveness faults, bias faults) and matched and unmatched uncertainties. Based on the fault model, a class of adaptive and robust tracking controllers are proposed which are adjusted online to tolerate the time-varying ...

Wavelength Component Analysis of the Pantograph-catenary Contact Force Based on EEMD-SPWVD

open access: yesDEStech Transactions on Computer Science and Engineering, 2018
The contact force between pantograph and catenary in high-speed railways is an important index to characterize the quality of current receiving. In this paper, the EEMD-SPWVD analytic method was proposed to analyze the inherent and abnormal wavelength components of pantograph-catenary contact force (PCCF).

The Generating Mechanism and Suppression Measure of the ‘Wheel‐Rail’ Rolling Arc for Electrified Trains

open access: yesHigh Voltage, Volume 11, Issue 2, Page 370-384, April 2026.
ABSTRACT As the ‘main blood vessel’ of the traction power supply system for high‐speed trains, the ‘wheel‐rail’ coupling grounding reflux system provides the vital channel to send traction current back to terrestrial substations; meanwhile, the rail track also plays a role in transmitting the train's occupancy signal to the control system.

Dual‐Frequency Piezoelectric Vibration Energy Harvester for IoT‐Based Real‐Time Freight Train Health Monitoring in Mongolia

open access: yesIET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study evaluates the potential of piezoelectric vibration energy harvesting to power IoT nodes for real‐time health monitoring of the Mongolian railway. Triaxial vibration data were collected at 500 Hz over a 400 km freight route under loaded and unloaded conditions using a custom ESP32‐S3 + MPU9250 system, and dominant frequencies were extracted ...
