摘要
针对半潜式海洋平台,采用最小二乘支持向量机(LS-SVM)回归算法辨识平台的逆模型特性,并将所得的逆模型作为控制器直接与平台模型相连,其中采用径向基函数作为核函数,对海洋平台三自由度的运动分别设计了相应的控制器;同时对其进行仿真、比较与分析。结果表明,这种控制算法具有很强的泛化能力和较高的精度。
According to the semi-submersible drilling platform, the least squares support vector machine （LS- SVM） regression is used to identify the inverse model of the platform,which using radial bases as a kernel function. Then the inverse model connects with the model of platform directly as a controller. There are three similar controllers for three degrees of freedom which are yaw, sway and surge. And the simulation results proved that the kind of controllers can keep the position of the platform in the deep sea during the motion of the system with the disturbances of current and wind.
