CONTROL METHOD FOR A FREE-PISTON ENGINE USING A PREDICTION CURVE AND A FREE-PISTON ENGINE CONTROLLED THEREBY

摘要

The present invention relates to a control method for a free-piston engine, comprising the steps of: acquiring measurement data containing a measured-position value and a measured-time value obtained by measuring the position and the time of a free piston at a specific point; acquiring calculation data containing a calculated-position value and a calculated-time value obtained by calculating the position and the time at the specific point from a predetermined standardisation curve; determining a prediction curve for predicting the pattern of movement of the piston after the specific point by subjecting the standardisation curve to conversion based on the measurement data and the calculation data; and controlling the free-piston engine by using the prediction curve, wherein a pattern of movement which is very similar to the actual pattern of movement of the free piston can be predicted, and the free-piston engine control performance can be improved.
