Free-piston diesel engine dynamics and control [PDF]

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
Free-piston diesel engines are characterized by freely moving pistons without any rigid crankshaft or camshaft connected to the pistons. This allows a highly compact and efficient engine design, but requires automatic control of the piston motion. This paper present a dynamic mathematical model of a free-piston diesel engine, a control oriented dynamic
