Large Free-Piston Stirling Engines

1985
The word ‘large’ applied to Stirling engines means different things to different people. An engine having a 3 kW output would be large to those working on artificial hearts or cryocoolers for electronic applications. It would be small, negligibly so, to those interested in locomotive propulsion.

Development of an In-Cylinder Pressure Observer for Free-Piston Engines

2018 IEEE Conference on Control Technology and Applications (CCTA), 2018
Reconstruction of engine in-cylinder pressure with observers in conventional engines has extensively been studied in the literature. The subject however remains unaddressed for Free-piston Engines (FPEs). An in-cylinder pressure observer suitable for FPEs is developed in this paper.

Dynamic Behaviour Prediction Of Free-piston Stirling Engines

Proceedings of the 25th Intersociety Energy Conversion Engineering Conference, 2005
The paper presents an integrated methodology for both the design optimization and the performance evaluation of free-piston Stirling engines (FPSE) suitable for space applications. In particular, the prediction of the dynamic behaviour is the problem here considered in more detail.

Control-based design of free-piston stirling engines

2008 American Control Conference, 2008
A control-based analysis and characterization of a free-piston Stirling engine is presented, and proposed as a lightweight power supply for untethered robots. Typically, such devices are designed from the point of view of a thermodynamic cycle in terms of traditional thermodynamic equations of state.

Modeling and predictive control of Free Piston Engine Generator

2015 American Control Conference (ACC), 2015
This paper focuses on the modeling and control of a Free Piston Engine Generator (FPEG) which is an alternative to conventional internal combustion engines to be used as an auxiliary power unit (APU) in hybrid electric vehicles (HEV). A physics-based, continuous-time model and a discrete-time, control-oriented model are derived.

Reducing Piston Mass in a Free Piston Engine Compressor by Exploiting the Inertance of a Liquid Piston

ASME 2009 Dynamic Systems and Control Conference, Volume 2, 2009
A dynamic model of a free liquid piston that exploits piston geometry to produce a high inertance was developed for use in a free piston engine compressor. It is shown that for the size scale targeted, advantageous piston dynamics can be achieved with a reduced piston mass compared to a rigid piston design.

Study on Piston Motion Control Strategy of Single Piston Hydraulic Free-piston Engine

2012 Second International Conference on Intelligent System Design and Engineering Application, 2012
This paper investigates the piston motion control strategies of a single piston hydraulic free-piston diesel engine, which is intended to be a power supply for hydraulic propulsion systems. The Cycle fuel mass is determined by engine displacement and load.
