This paper presents an approach to controlling the extreme positions of a piston in a free piston generator using linear electrical machine. The machine is used to provide the proper compression ratio necessary for ignition and limit the stroke of the piston in expansion phase. A Matlab/Simulink model, implementing the entire system, is presented. The results of simulation of the system show stable power generation within required movement boundaries of the piston.
