the method comprises the steps of obtaining position information through an output end of each linear power driving unit and/or a position obtaining unit on a wave making plate, obtaining rotation angle information through a shaft encoder on each linear power driving unit, checking the phase position of the output end of the adjacent linear power driving unit and/or the wave making plate according to the position information and the rotation angle information, and adjusting the phase position of the adjacent wave making plate according to the phase position to output a sine wave shape.
14. The method of claim 13, further comprising adjusting the frequency and height of the waves by adjusting the sine wave length and the speed of the wave making plate during wave making.
