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...

Towards self-powered lateral active suspension for railway vehicles (2014)
Presentation / Conference
Wang, P., Mei, T., & Zhang, J. (2014, July). Towards self-powered lateral active suspension for railway vehicles. Presented at UKACC International Control Conference 2014, Loughborough

This paper investigates the energy consumption of the lateral secondary active suspension for railway vehicles and studies the conditions for self-powered active suspension control. The influence of the performance index weighting factors to both the... Read More about Towards self-powered lateral active suspension for railway vehicles.

Detection and isolation for actuator failure for actively controlled railway wheelsets (2014)
Presentation / Conference
Mirzapour, M., & Mei, T. (2014, July). Detection and isolation for actuator failure for actively controlled railway wheelsets. Presented at UKACC International Control Conference 2014, Loughborough

This paper studies a model-based approach for the condition monitoring of an actively controlled railway system, with a focus on actuator failures to detect and isolate failure modes in such a system. It seeks to establish the necessary basis for fau... Read More about Detection and isolation for actuator failure for actively controlled railway wheelsets.

Railway vehicle optimisation to using the concept of design for control (2014)
Presentation / Conference
Ward, C., Mei, T., Hubbard, P. D., & Mirzapour, M. (2014, April). Railway vehicle optimisation to using the concept of design for control. Presented at The Second International Conference on Railway Technology: Research, Development and Maintenance ,, Ajaccio

Design for control is an axiom extensively used in the aerospace and automotive industries that has proven highly beneficial both in terms of performance benefits but also in reducing unit costs and reducing maintenance burdens. To date, in the railw... Read More about Railway vehicle optimisation to using the concept of design for control.

Fault tolerant strategy of actuator failure for actively controlled railway wheelsets
Presentation / Conference
Mirzapour, M., Mei, T., & Li, H. Fault tolerant strategy of actuator failure for actively controlled railway wheelsets. Presented at 2014 UKACC International Conference on Control, Loughborough University

This paper presents the development of a fault-tolerant scheme through an analytical redundancy approach for actively controlled railway wheelsets. The main aim of the study is to maintain the basic control of the rail vehicles in the event of actuat...
