摘　　要：借鉴陆上风力机基于状态空间法的干扰自适应控制,在状态空间中考虑海上浮式风力机支撑平台运动自由度,采用状态观测器评估系统各状态量,研究不同干扰自适应变桨距控制对海上浮式风力机控制性能的影响,并与FAST基础控制对比分析。结果表明:海上浮式风力机变桨距控制设计应基于状态空间法的干扰自适应控制,同时在状态空间中应考虑平台纵荡、纵摇及艏摇自由度。Using disturbance accommodating control based on state-space of onshore wind turbines,and considering the freedom of floating offshore wind turbine support platform in the state-space,and using state estimator to evaluate the system state variables,to research the influence of different disturbances accommodating control of pitch on the control performance of floating offshore wind turbine and compare it with FAST baseline control. The results shows that floating offshore wind turbine pitch control design should be use disturbance accommodating control based on state-space method,and the support platform surge,pitch and yaw freedom should be considered in the state-space.
