摘要
结合海上风机安装特点,以被动式软着陆系统为基础,建立了海上风机安装阀控软着陆系统的数学模型;按照吸收给定能量时峰值载荷最小的准则设计了模糊PD控制器。仿真结果表明,相对被动式海上风机安装软着陆系统,阀控软着陆系统能有效抑制海上风机的着陆时的加速度峰值,使得风机在恶劣海况下也可安全平稳地安装。
The mathematical model of valve controlled soft landing system has been presented based on passive soft landing system and a fuzzy PD control law has designed according to the control rule that the peak load should be as small as possible while the given shock energy is absorbed.Compared with the passive system,simulation results indicate that the valve controlled soft landing system can effectively restrain the peak acceleration of offshore wind turbine during landing and ensure safe and steady installation of wind turbine under atrocious sea condition.
