摘要

海上漂浮式风机服役环境复杂，为了在风浪载荷的联合作用下减少漂浮式风机的发电功率以及风轮转速的波动。在FAST基础控制的基础上提出了将分数阶比例－积分－微分(proportional-integral-derivative，PID)变桨控制，来抑制风、浪载荷的影响。以美国可再生能源实验室的5MW的OC4海上漂浮式风机为研究对象，首先建立了基于分数阶PID变桨距控制的漂浮式风机的动力学模型，结合遗传算法对控制的参数进行寻优，来提高系统的控制效果。使用了FAST与Simulink联合仿真，研究其对发电功率和风轮转速以及平台六自由度运动的影响，并且对变桨以后平台六自由度的运动进行了建模与分析研究。结果表明：与FAST基础PID控制器相比，基于遗传算法寻优的分数阶PID控制器具有更高的控制精度，有效降低输出功率和风轮转速的波动，而且会对六自由度的运动产生影响。

Abstract

The service environment of offshore floating wind turbines is complex, in order to reduce the fluctuation of the power generation of floating wind turbines and the rotation speed of wind turbines under the combined action of wind and wave loads. On the basis of FAST basic control, a fractional proportional-integral-derivative (PID) pitch control is proposed to suppress the influence of wind and wave loads. Taking the 5MW OC4 offshore floating wind turbine of the American Renewable Energy Laboratory as the research object, the dynamic model of the floating wind turbine based on fractional-order PID pitch control is established first, and the control parameters are optimized by combining with the genetic algorithm. to improve the control effect of the system. The co-simulation between FAST and Simulink is used to study its influence on the power generation, the rotational speed of the rotor and the motion of the platform with six degrees of freedom. The results show that compared with the FAST basic PID controller, the fractional-order PID controller based on genetic algorithm optimization has higher control accuracy, effectively reduces the fluctuation of output power and rotor speed, and has an impact on the motion of six degrees of freedom.
