METHOD FOR CONTROLLING FREE-PISTON ENGINE USING PREDICTION CURVE AND FREE-PISTON ENGINE CONTROLLED BY THE SAME

摘要

The present invention relates to a method of controlling a free piston engine, the method to measure the position and time of the free piston at a specific point to obtain measurement data including the measured position value and the measured time value; Steps to the previously calculated position and time of the specific point determined at the normalized curve to obtain the calculated data including the calculated position value and the calculated time value; Comprising the steps of: converting the normalized curve based on the measured data and the calculated data determining the prediction curve for predicting the motion pattern of the free piston since the specific point; And it may predict the motion pattern very similar to the actual movement pattern of the free piston comprises a step of controlling the free piston engine using the predicted curve, it is possible to increase the control performance of the free piston engine.
