| 摘 要： | 导管架式海洋平台在随机波浪等外载荷作用下极易产生有害振动,且其动力响应具有极强的非线性和时变性,采用被动控制方法和基于精确数学模型的主动控制方法控制海洋平台的有害振动很难达到理想的控制效果.结合灰预测和支持向量机的优点,提出了基于灰预测和支持向量机的自适应逆控制方法,并将其与动态刚度阵法相结合应用于导管架式海洋平台的振动主动控制中.数值算例分析表明,该控制方法可有效地控制波浪和风载荷作用下引起导管架式平台的有害振动,并能解决由于控制信号传输等原因引起的时滞问题.

| Abstract: | Offshore platforms usually experience harmful vibrations as a result of random natural loads.The dynamic response of the platform has strong non-linear and time-variant characteristics,so neither traditional passive control methods nor active control methods based on accurate mathematical models can effectively dampen the vibrations.A new kind of adaptive inverse control method,based on a combination of grey forecasting and a support vector machine,was developed and applied to control the vibration of offsh... |
