Method and system for creating surface waves in a body of liquid.

摘要

Method for controlling a reciprocating displacer (1) for creating surface waves in a body of liquid. The wave height (N) on the front face of the displacer wave board is measured. The corresponding height signal (11) is integrated in time (4) and subtracted from a wave board position determining control signal (6) which is dependent of the desired wave pattern to be created. The resulting signal (X) controls the drive means (7) of the wave board such that the signal determines the position of the wave board in relation to a reference (zero) position.
