摘　　要：基于S面控制算法给出了一种新颖的无反射造波策略.采用交流伺服控制技术,设计了单轴无反射造波机控制硬件系统,根据无反射造波控制算法与所用硬件产品的特性,编写了无反射造波控制软件.在简易水槽中进行了规则波的普通造波与无反射造波试验,并与以往的无反射造波方法进行了对比.试验结果表明:采用S面无反射造波方法时,造波机能够长时间地输出稳定的波形,与以往的无反射造波方法相比,S面控制算法体现了更好的吸收效果.给出的无反射造波机系统的设计方法可以为不规则波无反射造波的研究以及水池多轴造波机无反射造波系统的集成提供依据.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.
