Journal Article
YAN, Y., LIU, Y., JIANG, H., PENG, Z., CRAWFORD, A., WILLIAMSON, J., THOMPSON, J., KERINS, G., YUSUPOV, A. and ISLAM, S. 2019. Optimization and experimental verification of the vibro-impact capsule system in fluid pipeline. Proceedings of the Institution of Mechanical Engineers, part C: journal of mechanical engineering science [online], 233(3), pages 880-894. Available from: https://doi.org/10.1177/0954406218766200

This paper studies the prototype development of the vibro-impact capsule system aiming for autonomous mobile sensing for pipeline inspection. Self-propelled progression of the system is obtained by employing a vibro-impact oscillator encapsuled in th...

State switching of a multistable impacting system using PD-like control. (2018)
Journal Article
LIU, B., FUNG, W.-K. and LIU, Y. 2018. State switching of a multistable impacting system using PD-like control. MATEC web of conferences [online], 148: proceedings of the 2017 International conference on engineering vibration (ICoEV 2017), 4-7 September 2017, Sofia, Bulgaria, article number 10001. Available from: https://doi.org/10.1051/matecconf/201814810001

A new PD-like control law is proposed in this paper to control a multistable impacting system. This control law can switch the system from a current, undesired state to a desired one by using the differences of the displacement and velocity between t...
