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。 Combined with the installation characteristics of offshore wind turbines, a mathematical model of valve-controlled soft landing system for offshore wind turbines was established based on the passive soft landing system. The fuzzy PD controller was designed according to the criterion of minimum peak load for absorbing given energy. The simulation results show that the valve-controlled soft landing system can effectively suppress the peak acceleration of the offshore wind turbines when they are landed, so that the turbines can be installed safely and steadily under the adverse sea conditions.
