Benefits include improved thermal and mechanical efficiencies, multiple fuel capability due to the free-piston dynamics and variable compression ratio, and higher power-to-weight ratio due to single-moving part and compact design. Coupled to a linear electric generator (LG), the resultant system is a free-piston linear electric generator (FPLG)-an alternative power source for vehicle propulsion and portable power generation. This paper discusses control issues of the FPLG and proposes an electrical solution to achieve sustained operation in the face of combustion variation and engine misfires. It presents simulation results on the effect of varying output load current on piston trajectory, for viability of automatic control in an otherwise unconstrained FPLG. © 2020 IEEE. date: 2020 publisher: Institute of Electrical and Electronics Engineers Inc. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85097788771&doi=10.1109%2fSCOReD50371.2020.9250983&partnerID=40&md5=fd8131bcd64aac38caf9c7e7df4369ef id_number: 10.1109/SCOReD50371.2020.9250983 full_text_status: none publication: 2020 IEEE Student Conference on Research and Development, SCOReD 2020 pagerange: 465-470 refereed: TRUE isbn: 9781728193175 citation: Bashir, A. and Zulkifli, S.A. and Abidin, E.Z.Z. and Aziz, A.R.A.
