摘要: 本文所述系统可在水池中产生单一频率规则波、周期不规则波及"随机波",用于海洋、造 船工程的模型试验,采用频域迭代法和成型滤波器法来产生模拟海浪.尽管这一控制系统是 专为产生模拟海浪而设计的,但其控制方案也可直接用于其他测试技术领域,以产生"随机" 信号.Abstract: The system, which consists of an electro-hydraulic servosystem and a microcomputer-based controller, is used to generate single frequency, periodic and randow waves in a water tank. Two approaches, the recursive approach and the shaping filter approach, are used. Although the system is specially designed for simulated ocean wave generation, the control scheme can also be directly applied to generating random signals in many other fields of test engineering.
