IET Power Electronics, Volume 16, Issue 14, Page 2287-2300, 4 November 2023., 2023 Interharmonics on the grid‐side of the traction power supply system can propagate through the electric traction drive system to the mechanical transmission system, causing torque ripples and vibrations of key train components. An improved passivity‐based control is designed for the inverter‐motor system of the high‐speed train in this paper to suppress

IET Electric Power Applications, Volume 17, Issue 10, Page 1321-1333, October 2023., 2023 This paper presents a torque distribution control strategy for electrical trains equipped with driven independently rotating wheels to realise the coordination of guidance control and adhesion control. The torque distribution strategy proposed can achieve the traction/braking and guidance function on the adhesion limit.

Mitigation of transient torque reversals in indirect drive wind turbine drivetrains
Wind Energy, Volume 26, Issue 8, Page 803-825, August 2023., 2023 Abstract Bearing failure in wind turbine gearboxes is one of the significant sources of downtime. While it is well‐known that bearing failures cause the largest downtime, the failure cause(s) is often elusive. The bearings are designed to satisfy their rolling contact fatigue (RCF) life. However, they often undergo sudden and rapid failure within a few
