The active absorbing wave maker can immediately eliminates interference effects on the model tests, which ensure the accuracy of the test results. Basing on Airy wave theory, active absorption wave-making method is put forward, and control equation of rocking-plate wave maker is derived. Active absorbing wave-making control system is designed, based on the wave method. Through multiple feedback lines, a precise control of the wave maker is achieved as well as the real-time absorption of interference wave before the wave blade, which ensures wave is the target one in the sink. Finally, under the same wave conditions, contrast testing is conducted between the active absorbing wave method and non-active absorbing wave method. It fully verifies the feasibility and timeliness of active absorption wave-making method. The realization of active absorption wave maker helps to improve the accuracy of wave experiments, to save test cost, and to provide a good test environment.
