Abstract：The electric control system
of free piston linear generator was designed using LabVIEW. The function demand
of the control system was analyzed. The selection and constitute of hardware
for the control system was proposed. Based on modularization method, the
LabVIEW program was divided into signal processing module, status switching
module and Injection-Ignition module. A control strategy of motor force was
designed for continuous running of the system. The experimental result shows
that the control system designed using LabVIEW could fulfill the precision and
punctuality controlling of the free piston linear generator.
