Application of state estimators in active control of railway wheelsets (2019)
Presentation / Conference
Weerasooriya, L., Mei, T., Li, H., & Luo, Y. (2019, August). Application of state estimators in active control of railway wheelsets. Presented at 26th Symposium of the International Association of Vehicle System Dynamics, IAVSD 2019, Gothenburg, Sweden

This paper presents the development of a state observer for the estimation of output torque of an electromechanical actuator in the application of active wheelset control for railway vehicles. The output from the state estimator is essential to ensur... Read More about Application of state estimators in active control of railway wheelsets.

Control of railway wheelsets – A semi-active approach (2019)
Presentation / Conference
Mei, T., Zaeim, A., & Li, H. (2019, August). Control of railway wheelsets – A semi-active approach. Presented at 26th Symposium of the International Association of Vehicle System Dynamics, IAVSD 2019, August 12-16, 2019, Gothenburg, Sweden, Gothenburg, Sweden

This paper presents a detailed study of semi-active approach for railway wheelsets. A number of control strategies for active primary suspensions for both solid axle wheelset and independently rotating wheelsets are examined in detail and the key req...

Rotor-position detection in permanent-magnet wheel motor to ensure smooth startup from standstill (2019)
Journal Article
Qu, K., Li, W., Xu, G., Mei, T., Cao, J., Zhang, Y., & Hu, H. (2019). Rotor-position detection in permanent-magnet wheel motor to ensure smooth startup from standstill. IEEE Access, 7, 54179-54191. https://doi.org/10.1109/ACCESS.2019.2912445

In this paper, an innovative rotor-position-detection method for a permanent-magnet wheel motor (PMWM) that operates from standstill to low speed is presented. The neutral voltage, which is sensed through phaseshifted pulse width modulation, overcome...
