Based on the S plane control(SPC) algorithm,a novel active wave absorption method is proposed.By using the alternating current(AC) servo control technology,a single-axis control hardw are system for active absorbing w ave-making is manufactured,and the control softw are is compiled according to the active absorbing algorithm and the product characteristics of the servo motor.The absorption and non-absorption w ave-making contrast tests for regular w ave are carried out in a simple w ave flume.The SPC algorithm is compared w ith and the prior active w ave absorption method.The experimental results show that by using the active w ave absorption method based on the SPC algorithm,stable w ave profile can be output by the w ave-maker in a long time.Meanw hile,the SPC algorithm performs superior to the prior method w hen using SPC.The proposed method can be used as the theoretical basis for the research on irregular w ave and integration of active w ave absorption systems of multi-axis basin’s w ave-maker.
